The seats are very uncomfortable..
Haven’t flown in a very long time, was kind of scared but flight was ok pilot was very friendly and I was quickly at ease. Thank you
Checked bagged was delivered extremely quickly! Smooth flight, great staff.
Thank you for getting to my destination safely
Seats are too small!
A flight at an adjacent gate was delayed and United brought out a cart of water bottles and snacks for them. I thought that was a nice gesture.
No free sodas and no reclining seats?!
My seat was right where people kept bumping into me. Super annoyed. Very unpleasant ride
I asked for a seatbelt extender 3 times and I couldn’t buckle my seat belt until the plane got into the air. That’s unsafe
Over 30 minutes late departing and once on the plane a flight attendant was yelling at a passenger, screaming “Listen to me!! I’m not rude!!” Really? Very unprofessional.
The extraFees for carry out was extremely disappointing & Terrible quality of seats made the trip even worse
So far this year you have scored 100% never on time, good job.
Unexpected baggage charges not showing during booking
TERRIBLE CUSTOMER SERVICE NEVER FLY THIS AIRLINE AGAIN!!!
