This Flyertalk thread alerted me of the new 50,000 sign-up offer for the Chase Sapphire card. It's not clear if this is a officially sanctioned offer by Chase yet.
The fee has increased to $125 but it's still waived for the 1st year.
I had both version of this card (there is also a Mastercard version that often carries the same bonus).
I love the card because:
– it (still) looks super cool
– there are no foreign exchange fees
– double points on all dining and travel purchases
While United may not be the best mileage currency anymore Ultimate Rewards has a ton of travel partners to transfer points on a 1:1 basis to.
If you get the card soon and the complete the minimum spend as well you can still redeem using the old award chart before the January 31st deadline that United airlines has given us.
