Alaska Companion Fare Hawaii 2026: $99 vs Separate Tickets — Book or Split?

Read the cash-cost row first, because it decides most Hawaii trips. If the cheapest separate round-trip fare for the second traveler is several hundred dollars — which peak-season Hawaii fares routinely are — the companion fare wins by a wide margin even after you add taxes and fees. The Points Guy reports U.S. airlines raised checked-bag fees by roughly $10 in March and April 2026, so budget for that on whichever option you choose; it applies to both paths and does not flip the result.

Separate tickets win in one specific scenario: when the voucher's fare-class restriction forces you into a booking class priced far above the lowest available separate fare. That happens on dates where the eligible fare class is sold out or heavily priced, while a cheaper fare sits in a class the voucher cannot touch. Before your code expires, price the same Alaska round-trip itinerary two ways — one reservation with the companion fare applied versus two separate reservations — and compare the second traveler's total under each.

Quantify the gap before deciding. Take the companion option's total for the second traveler ($99 plus taxes and fees, plus any fare-class premium on the first ticket) and subtract it from the cheapest separate round-trip fare you can actually book for those exact dates. If the difference is comfortably positive, book the companion option now, before the code expires. If the gap is thin or negative — meaning the voucher is pushing you into a fare class that erases the savings — two separate tickets are the better buy, and you keep the voucher for a pricier date.

One last check on flexibility: if either traveler might change dates independently, remember the companion fare locks both of you into a single reservation. Two separate tickets cost more upfront but decouple your itineraries — a trade worth paying for only when a schedule change is genuinely likely.

Costs and Numbers That Matter

The companion fare's headline number is $99, but that figure is only the base. Per NerdWallet, the Alaska Companion Fare lets you book one round-trip coach fare for the second traveler at $99 plus taxes and fees, on the same reservation as a paid ticket. Treat the $99 as round-trip, because the voucher covers a round-trip coach fare — not a one-way segment. Taxes and fees are not included in that $99, so the true companion cost is $99 plus whatever taxes and fees apply to that itinerary. Before you compare anything, pull the actual tax-and-fee total for your specific Hawaii round trip; that number, not $99, is the companion side of your comparison.

Bag fees are the second layer, and 2026 made them worse. The Points Guy documents that many U.S. airlines raised baggage fees in March and April 2026 by about $10. That increase does not hand you Alaska's exact first- and second-bag figures, so do not assume a number — check Alaska's current checked-bag fees on alaskaair.com before you total anything. Then run the math for your party: if two travelers each check one bag round trip, multiply the applicable per-bag fee by the number of bag-legs you will actually pay for, and add that to both sides of the comparison. Bag fees hit the two-separate-tickets option and the companion-fare option differently only if the fare classes you compare include different bag allowances, so confirm the allowance attached to each fare before you add fees.

The hidden number is the fare-class gap. The voucher is not valid on every fare class; the lowest eligible fare class for the companion fare is often higher than the lowest cash fare you could book separately. That gap is the real cost of using the voucher, and it is the figure most travelers never calculate. Price the same Alaska round-trip itinerary two ways: one reservation with the companion fare applied, and two separate reservations at the lowest cash fares available. If the difference between the lowest eligible voucher fare class and the lowest cash fare exceeds $99 per person, the companion fare is likely the weaker deal once you also account for the flexibility you give up.

Cost layer	What to enter	Source / check
Companion base	$99 (round-trip coach fare)	NerdWallet
Taxes and fees	Actual taxes/fees on your itinerary	Alaska booking flow
2026 bag-fee increase	About $10 higher across many U.S. airlines, March–April 2026	The Points Guy; verify Alaska's exact fees at alaskaair.com
Fare-class premium	Lowest eligible voucher fare class minus lowest cash fare, per person	Your own two-way price check

Add the first three layers to get the companion's true cost, then compare that total against the second traveler's separate round-trip fare. If the separate fare is less than your stacked companion total, book two separate tickets. If it is more — and the fare-class premium you are paying stays below roughly $99 per person — the companion fare wins. Run this arithmetic before your code expires, because the answer changes with the itinerary, the fare class, and the bag count.

What the Evidence Does Not Establish

Before you commit, be honest about what the evidence above does and does not establish. The sources describe the companion fare's structure, but they do not state the current expiry window on your voucher, which fare classes qualify as the paid ticket, or whether the code applies to award travel. None of that belongs in this article — it belongs in your Mileage Plan account. Sign in, open the benefit details, and confirm all three before you plan anything around the code.

The clearest break point is one-way or open-jaw travel. NerdWallet documents the companion fare as a round-trip benefit, and the companion rides on a single reservation matching the paid traveler's itinerary. If your Hawaii plan has one traveler flying one way or two people returning on different dates, the mechanism itself breaks — the companion cannot be split off onto different flights within the same booking. In those cases, two separate tickets remain the only option, and no comparison is needed.

So the decision is not universal; it is conditional. Use this table to sort your situation before pricing:

Scenario	Companion fare wins when...	Separate tickets win when...
Identical round-trip dates, both travelers together	The second traveler's separate round-trip fare exceeds $99 plus taxes, fees, and any flexibility you give up	Separate round-trip fares for the second traveler price out lower than the single-reservation total
One-way or open-jaw Hawaii plan	Not applicable — the voucher is documented as round-trip only	Always, because the companion structure cannot support it
Travelers returning on different dates	Not applicable — both passengers share one reservation	Always, because split itineraries require split tickets
Checking bags in 2026	The fare gap is wide enough to absorb the bag fees The Points Guy reports U.S. airlines raised by roughly $10 in early 2026	Bag fees swing the math when the fare gap is narrow

Notice what the table does not answer: your exact numbers. The head-to-head winner depends on live fares on your dates, and those change constantly. The method stands regardless — price the identical Alaska round-trip itinerary two ways, one reservation with the companion code applied versus two separate reservations, and let the totals decide.

One caution on timing: your voucher carries an expiry date, and the sources here do not state how far out you must book or fly within it. Check the deadline in your Mileage Plan account first, then run the two-way pricing while the code is still valid. If the companion option loses on your dates, you have lost nothing but a few minutes; if you skip the check and the code lapses, the decision makes itself without you.

Seattle to Honolulu

Here is the only worked example in this guide with named checkpoints, using a two-traveler, Seattle-to-Honolulu round trip with one companion fare voucher. Run it before your code expires, because the answer changes with fare availability and you want the comparison done on live prices, not memory.

Checkpoint 1: pull the lowest eligible fare class on alaskaair.com for your dates and note the round-trip price. Say it comes back at $450 round trip per traveler. That is the fare the voucher anchors to — the $99 companion price attaches to a coach fare you pay on the same reservation, per NerdWallet's description of the structure.

Checkpoint 2: price the exact same dates as two separate reservations and take the cheapest combination, even if the two tickets are in different fare classes. Say the lowest separate round-trip fare is $380, so two tickets cost $760 before taxes.

Checkpoint 3: add taxes and fees to both paths and the current checked-bag fees. Note that U.S. airlines raised checked-bag fees by roughly $10 in March and April 2026, per The Points Guy, so check the live fee on alaskaair.com rather than assuming an older number. Since the companion travels on the same reservation, apply the bag fee to each traveler identically in both columns so the bags don't distort the comparison.

The decision math: companion path is $450 plus $99 plus taxes for two; two separate tickets is $760 plus taxes for two. Before taxes, the companion path saves $760 − $549 = $211. Taxes apply to both paths, so the gap narrows slightly but the direction is unlikely to flip at this fare spread. If the eligible fare class had come back at $500 and the separate fare at $380, the gap shrinks to $760 − $599 = $161 — still companion, but with less margin for the flexibility you may give up.

The cost of being wrong runs in both directions. Book two separate tickets when the companion fare would have won, and you pay the difference out of pocket — $211 in this example. Book the companion path when the separate fares were cheaper and in more flexible classes, and you may be locked into a restrictive fare-class ticket on a single reservation where a date change reprices both travelers together. That is why checkpoint 2 must use the same dates and the cheapest available combination, and why you run this the day you intend to book: pull both prices, add taxes and bags, and let the totals — not the headline $99 — make the call.

Decision Rules: Book or Split

If the voucher's eligible round-trip coach fare class is within $99 per person of the lowest separate round-trip coach fare, book the companion fare — the second seat is effectively $99. In that case, you are not giving up enough value in fare class to outweigh using the voucher on this itinerary.

If the eligible round-trip coach fare class premium exceeds $99 per person, split into two separate tickets and save the voucher for a peak-date trip. Do not force both travelers into a higher eligible round-trip coach fare class just to use the voucher if buying two separate round-trip tickets would be cheaper for the pair.

If either traveler needs different dates, a one-way, or an open-jaw, split — the voucher only covers same-itinerary round trips. With those structures, the comparison above cannot apply, so the correct move is to not force the voucher onto an itinerary it does not cover.

What to do next

Step	Action	Why it matters
1	Check the expiration date on your Alaska companion fare code before doing anything else.	The code is only usable before it expires, so the whole two-way comparison has to happen inside that window.
2	Price the SAME Alaska round-trip itinerary to Hawaii as one reservation with the companion fare applied — the second traveler rides for $99 plus taxes and fees.	This is the companion side of the comparison, and it only counts if the itinerary is identical to the separate-ticket option.
3	Price that identical round-trip as two separate reservations and note the lowest fare you can actually buy for the second traveler.	The separate-ticket fare is the benchmark the $99 companion fare has to beat on the same itinerary.
4	Compare the two totals, factoring in the fare class and flexibility you give up when the companion fare is applied.	The companion fare wins when the second traveler's separate round-trip fare exceeds roughly $99 plus that lost fare-class and flexibility value.
5	Apply the decision rule: book the companion option unless the cheapest eligible fare class is more than $99 per person above the lowest separate-ticket fare you can actually buy.	This threshold keeps the call mechanical — no guessing once both prices on the same itinerary are in front of you.
6	Book the winning option on the official Alaska site before the companion fare code expires.	Locking in the cheaper of the two configurations while the code is still valid is the whole point of the comparison.
