Not up to the major airlines standard – British Airways Review

It still appears BA is unable to produce an application for iOS (or web) that works consistently and reliably. It’s been a multi year effort with little improvement thus 2 stars not 1. You can go and check-in only to be told you can’t get your boarding passes due to passports/visa verification. You go in through an alternate route and behold boarding passes abound. Then it refuses your partner’s boarding pass and you have to log in with their BA app to get a boarding pass - funny not haha. Just one of many bugs as the iOS app switched in and out of web mode. Just sloppy execution and negligent QA.
Review by bad BA just bad on British Airways.
