lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

They needed people to check a bag, they did check my bag and I had to wait 10 minutes after the flight to get it it wasn’t too bad

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

Cramped seats. Audio jack for the in -flight entertainment was broken.

Flight was great albeit the long line before the int’l immigration given the timing of the year.

They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA
