Ottawa Airport is easy to navigate, but small bins may force gate-checked bags.

Ottawa, as a small airport is easiest to navigate! Overhead baggage compartments seem to be smaller, and on every flight they seem to need travellers to volunteer to put carryons in checked luggage instead.

I always expect issues with United but there doesn't seem to be another airline to use. Advice: Give yourself and extra day to get anywhere - don't be in a hurry to get home either.

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

Poor communication, flight was delayed for preventable reasons. I missed my connection.
