First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

Late- that’s what United does best. Missed my connection, rebooked to a flight 17 hours later and had to spend $500 on a hotel. What did I get? A $15 meal voucher. What can you get in an airport for $15. I hate United so much.

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

Horrible, absolutely horrible. The airline overbooked the flight, did NOT assign seats and boarding was a hot mess with lots of confused passengers. There was no "large plane" gate for us, the 500+ passengers were squeezed in a small hold room area, and multiple busses had to shuttle us to the other side of the airfield, where boarding of the plane, that was parked on the ramp, took place in rain. The old plane had a broken seat, that the technicians tried to fix - with no success - resulting in a 50min delay. The flight attendant with heart shaped earnings with German flag was screaming on the passengers without a reason, was extremely rude and entitled the entire flight. The food was junk. I hope I don't have to fly United ever again.

Quick boarding. We left on time even though the plane came in late.
