The App was and is still useless. It offers me only two features of note, one of which is accidental when they updated it. I can open the booking fairly quickly and notice that seat reservations dropped off because the aircraft was changed and secondly, it enables mobile boarding passes in stations that are on Altea but don't offer mobile BP- this is purely by accident. They made it worse by removing the ability to go back into checkin once a BP is issued.
Sometimes PNR's get removed from the online account so it's not even that great for keeping a record of your PNR's.
For seat changes post-OLCI, you're better off saving the OLCI link to your phone
https://checkin.si.amadeus.net/stati...identification and then you can change your seat once you're checked in much quicker and easier. Btw, you can change the two letter carrier code to the likes of A3, TP, JL, AY, MS, ME etc who all use the same out of the box setup.
