The version from last year was much better.
It had more options available in full web version, like upgrading your flight features.
This new version does not have it (or is hard to find). It also doesnt allow you to save personal information. You cannot enter just e-mail address, or just phone number. You have to fill out whole page, and when you enter expiration date of your document it insists that your passport expired (which is not the case), so check the calendar setups.
The reservation check is pretty slow. Once you enter confirmation number, last name and hit "check" you stare at the blank page.
Please fix this frustrating app.
I gave two stars for visual design.
