Nice app till you start entering credit info

Tried to buy premium economy upgrades with my credit card. Expiration year cannot be entered b/c the value is from 24 to 34.
The authorization fails, and I would have to do it over with PC.

If this isnt a conspiracy to stop me from upgrading, fix it ASAP. Then I will give a 5 star.
