Broken tray table. Erratic service. Premium economy is more economy than premium- other airlines treat PE much better. No lounge access.

Broken tray table. Erratic service. Premium economy is more economy than premium- other airlines treat PE much better. No lounge access.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

We had a delay, but thankfully I made it to my connection. Overall it went smooth

The flight had a delay but I made it to my connection. Flight was smooth overall

As I wrote earlier, poor planning and/or communication. At least twice, we were told that we would be boarding in less than ten minutes, only to have the flight again delayed at least another hour.

Our flight from Nice to Newark ran an hour late, and the food was mediocre, but it was fine. The problem was that we were scheduled to have a 4.5-hour layover in Newark, but then our flight to RDU was almost four hours late, finally departing at almost 11:30 p.m. We understand that flight delays were caused by weather problems in the East. However, there were at least two times, when were told that we would begin boarding in just a few minutes, only to have the flight delayed another 1.0-1.5 hours. This meant that we would leave a restaurant or the United Club, go to the gate, only to learn that there would be another major delay. Poor planning and/or communication.

This flight is a quick way to get to Chicago, but a bit expensive.

There were no facilities in the middle of the aircraft and premium economy was not allowed to use the business class facilities, and had to share the only two toilets at the back with economy. The upgrade to Premium was definitely not worth it

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.
