This is the worst app ever. The passport scan upload can take up to 5 minutes, and, ladies and gentlemen, it will. And then it said there was an error. I have been trying to complete the whole procedure for over 2.5 hours now and I give up. I made it through 5 times to the very last step (hazardous goods) and then " unable to complete checkin" Iit's worse than Hotel California. I cannot checkin at all! So here we go, back to the Stone Age and wait in line with your small kids. Seriously?
