There is no one clear process anymore.
Last week I went to board a flight and checked in using the phone app. At the airport I needed to get a baggage ticket so I used the machine there for that, but it basically had me go through the whole check-in all over again. On top of that the first machine errored during the step to pay the baggage fee so I ended up doing that again with another machine.
Afterwards I went to drop off my bag and was told the tag was not "active" and I'd have to go to the desk.
What the hell is the point of any of these electronic options if at the end of it all I still have to wait in line for an agent, stand there while they "mmm-hmmm" at their computer and avoid eye-contact with me for 5 minutes just to finally scan the tag I had printed and attached myself?
