They rescheduled me and I had no issues with the new flight

No paper towels in bathroom. Aisle seat difficult to get out of Other than those, excellent service

Both flights are delayed so I rate the whole experience as mediocre.

Bad experience boarding and flight got delayed didn’t make it to my next flight

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

Excellent crew, great food despite catering issues. We need more people like this.

1. The PA system was painfully loud. 2. Overhead bin #33 was missing—I find this troubling.

This leg was run by United. Food was ok and the regular menu was actually not good ( Hindu meal was fine). Crew was fantastic
