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.

We were very offended Reserva check in agent in Calgary. Erroneously profiled and reprimanded for using Reserve line . Hadn't even looked at tickets. We were in fact Reserve passengers

There was No Flight. Both Kayak and Porter refused to honor my booking. I was asked for an additional 1,300 $ CAD to keep the flight. After several emails to both Kayak and Porter I was ignored. I had to cancel my March spring break plans, dog kennel and hotel. I had to re-book another vacation to Nassau in January w Expedia. I had to re-book a new vacation for spring break. Porter and Kayak both blamed each other and would not work together to fix this. Not cool.

Even tho the flight was a bit delayed the team was apologetic. Everyone was friendly and efficient.

The flight booking code given by Kayak was not the correct one used by the airline. I had to call to get the correct one. It was never sent to me. Totally unacceptable!

I like it, but the food isn't good. They need to offer more simple things. This bowls that have so many things your don't know what your are eating. The milenials like it, no the rest. And last but not least, they allowed somebody have a huge dog, vey agressive and fidgety in the flight. That's horrible. No animals should be allowed inside the airplane, what about allergies, etc

There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!

Great! Personable crew. I love that they pour complimentary beer and wine.

The E195-E2 is a great aircraft! Leather seats, lots of legroom and SO quiet! The flight crew is terrific!

Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.

travelling in 14th of April and now we are in 17th , I have not received my lost/delayed bag... this is very bad and the worst part is their call center is not able to see where is it!!!!

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Entertainment kept turning itself off. Gave up on watching a movie.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Not United Airlines' fault. It's ORL airport's fault.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

The flight was on time and the crew were great.

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

West Jet flight was cancelled and I was not notified. I found out when I tried to check in on-line. Spent 4 hours on the phone with West Jet and Just Fly trying to figure what happened.

It was good, flight was on time, boarding was smooth and done in zones, food was good too but there was no form of entertainment. Luggage’s were intact. So an overall good flight

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Flight was on time. Online check in capabilities made things quick and easy. Zone boarding was enforced, which I appreciate. Everyone was not lining up ahead of their zone being called. Crew was professional and friendly.

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

It was okay overall, but it was a 4 hours flight and the only thing we got was snacks, I really expected breakfast.

My wife and I both use canes. Although I had checked in 24 hours before the flight and noted we would be checking two roll-on bags, the machines at the check in area did not produce luggage tags, and staff were unwilling to help unless we joined the long queue, a very difficult challenge. We opted to take the bags on board and, of course, were relieved of the jells and scissors in the bags at security. On board crew were then unhelpful in hoisting the bags into the overhead bins.

I liked the fact that we arrived on time. What I did not like, I paid for a seat. Unfortunately a very large women sat beside me (required a belt extension). Her body spilled to my side. Not her fault but I had to lean to the left because her body was literally on my side of the seat. This caused a back ache. I was unable to sit straight the entire flight. There should be some form allowance (wider seat) for morbidly obese passengers. These seats are not designed for extremely obese people. I feel compassionate towards these obese passengers but I got off the plane with a substantial lower back ache. I myself have a degenerative disk disease and this did not help me

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Very tight seats - no legroom at all, very tight to the person in front of you. If you have basic fare, you are loading zone 6 regardless of where you are sitting in the plane - meaning even as a middle aisle person at the front of the plane, I had to get people to get up and let me in as they had boarded earlier. Having to pay for a carry on is criminal. I am a frequent flyer, and air Canada has now joined the list of other terrible North American Airlines.

This flight didn't happen for me because of overbooking.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

Your survey should include a "Not Applicable" response for those elements that were not utilized, such as food (unless your want me to rate the cookie I received) and the entertainment (unless you want me to rate the emergency landing presentation). Boarding was late, the plane took-off almost an hour late, and the gate to board changed five times while I was waiting there. At 1:00 pm the plane had not yet approached the gate for passengers to load, yet the information board indicated that the take-off would be 12:30 pm and its status was "on time". Curious.

Not cancelled the flight I had to rebook with another airline

The flight was delayed for an hour and there was no inflight service.

One stewardess a bit to impatient with older Asian couple.

Seats are too close together. I'm 5'8" and could not sit comfortable the entire flight. I will not book Rouge again because of the leg room.
