Cons: "When landing on final approach close to the ground, the pilot pulled up and passed the airport. It was almost 10 minutes before he got on the intercom and told us what was going on. Apparently traffic control told him there was a backup and to circle around. Not knowing what the situation was, was very nerve racking. It would have been nice to hear an announcement of the situation sooner."

Pros: "Nothing"

Pros: "It was overall ok , but over all disappointing that west jest became such a budget airline."

Pros: "Air Crew was professional and polite - flight was quick and lasted less than 90 minutes in the air, was overall enjoyable"
Cons: "Gate attendant was fairly rude (could be a result of holiday travel stress) - several travelers didn’t speak English fluently, and she would snap at them or roll her eyes they weren’t comprehending instructions. Boarded extremely early (almost an hour) but sat on tarmac for some time - eventually took off about 20 minutes late. Not airlines fault and likely result of holiday backlog Retrieving baggage from plane was biggest issue - use a carry on to but was required to valet bag as opposed to storing overhead. Baggage unloading was late (again, holiday backlog) but no personnel were available to inform passengers of delay, and bags were not in initial cart. Resulted a delay of offloading by roughly 20 minutes. Was ultimately found in the second wave of luggage, and witnessed baggage handlers tossing luggage carelessly onto cart floor. Nothing was damaged but was annoyed at lack of communication and overall disorganization."

Pros: "Seat extraordinarily comfortable"

Cons: "Food quality"

Pros: "No amazing crew, just average. The should airline should have follow through on a specific request, but the airline's computer wipes out such things."
Cons: "Airlines should listen to the requests of the passengers."

Cons: "Seat space"

Pros: "On time,"
Cons: "WiFi didn't work."

Cons: "Typical tight seating, aircraft showing age."

Cons: "Better communication about handicap persons. I called twice and notified two people about my mom and her wheelchair but no one tells the gate to put a ramp up to the regional jet on the tarmac. Three ring circus as usual ."

Cons: "The wifi signup process not seemless with Android."

Pros: "The crew was super nice and I saw them be super accommodating to other passengers which made me feel good about using their airline."

Cons: "I’m not sure how this flight was as I missed it due to a delay from YYZ to ORD"

Cons: "Boarding at Terminal 3 gate A8 was slow and a single line makes for a lengthy process."

Pros: "My connecting flight from london arrived late and the crew made sure i made it onto the flight to stl even though I barely made it to the gate on time."

Pros: "My flight was fine - I paid for a Premium Seat, which also allowed me a premium boarding position, which I highly recommend for anyone flying. The seat was comfortable, the staff was very friendly and I really liked the in-flight entertainment."
Cons: "At the DFW security post for my gate, there was NO TSA-pre. That service stops at 7pm. I would think at a major airport like DFW where American Airlines has a hub, they would make sure to staff that longer. Just getting to keep my shoes on, while having to drag all my electronics and liquids out, take my coat and belt off, etc. is not acceptable. AA should put the pressure on DFW to treat their customers better!"

Pros: "Flight was pleasant and all the crew members were courteous."

Cons: "Staff seemed tired with some minor conflicts between them at Toronto gate"

Pros: "It was easy to travel"

Pros: "Friendly crew"
Cons: "Zero Entertainment. Flight delayed around 30 minutes, which gave me a heartburn as we had to catch the next flight. No priority plus lounge near this gate in Toronto"

Cons: "Too many delays. Having to de-board after boarding."

Pros: "The middle seat was empty I had an aisle seat. That was wonderful."
Cons: "No wifi screens for books or movies but I had my iPhone."

Pros: "I liked having a window seat."

Pros: "On time"
Cons: "Boarding numbers"

Pros: "My neighbor."
Cons: "We sat on the tarmac for over an hour for no apparent reason."

Cons: "I nearly missed my flight because I did not have a seat for a flight that I bought a ticket for at full price. Which, would lead one to believe that I would have a seat on said flight. However, coming to the gate an hour before boarding the personnel working gate the said he was having computer difficulties and could not get me a seat and it would be 10 min. I continued to return till boarding to find out I had no seat and I was on standby. Upon going to customer service they replied the airline oversold tickets and every airline does this as if to make this practice ok. Well being in sales myself and if I were to sell x amount of product to one customer ( or several) I better make sure I have it all there to deliver. People rely on you schedule wise. It nearly shot a meeting I had to make in the foot. Very disappointed with the airline and the way things were handled."

Cons: "Forced to check my carry on. Took 30min for the bags to come out on the carousel. Which is why i never check my bag."

Pros: "very friendly staff"

Pros: "Nothing to expect from Domestic fight."

Cons: "Boarding was chaotic, with people sitting in wrong seats and walking the wrong way down the plane. Crew were not especially friendly. I know it was at the tail end of a long Sunday, but it wasn't impressive."

Pros: "Plane was ancient"

Pros: "Entertainment, 110 plugins for devices, internet."
Cons: "only free meal option was cinnamon cookies."

Pros: "Flight was on time. Plane was clean. Staff very professional."

Pros: "Nice crew."
Cons: "Would have liked some better movie choices."

Pros: "Flight crew was vey nice and flight was on time."

Cons: "We did not make this flight due to the first flight being over an hour late. This caused us to miss our connection to St. Louis. While they rerouted others on the flight, they did not reroute us because we didn't check any luggage! Their reasoning was we had a chance to make the connection. But they made us wait in a line for 10 minutes to be told that despite our requests to go to the gate. By then it was too late. We then had to fly stand by to Chicago and stand by again to get to St. Louis."

Pros: "none"

Cons: "I am not a large person, 5'4, size 8. I was uncomfortably cramped in my seat. How do they expect normal sized humans to fit here??"

Pros: "Everything on time"
Cons: "Nothing"

Cons: "After crossing in a 787 from Zurich this small older jet to Austin looked and felt like 15 years ago. Bathroom was bad for a 6'2" guy."

Pros: "The crew was great"
Cons: "Broken toilet for this flight"

Pros: "The food was airline food, the movies worked"
Cons: "Given customs form in German, when asked for English flight attendant said they were out. asked another later and she brought it immediately. After herded through security (again) and customs, with no explanation on what to expect, our connecting flight's gate was in the basement. It looked like a third world bus station. No place to sit, totally packed, could not understand announcements, only bagel place to eat that was out of most everything. I will avoid Air Canada and Toronto airport if at all possible."

Pros: "It got to Vegas on time and my luggage was there, too."
Cons: "Rouge has less space per person than Spirit. I never thought that could be possible."

Pros: "Not really stands out as a positive."
Cons: "Overall came across as not up to the standards of other carriers."

Cons: "They didn't even let me check in. Spent 12 extra hours at the airports to get home."

Pros: "Traveling back to the US have Global Emtey or Nexus Like the free movies watched half of movie on the way to acanandr and half on the way back. Thank you"
Cons: "Last time I traveled to Canada I probably used a passport. BUT I never knew that I needed it I thought u could travel with my drivers lisence. Remind travelers to take their passport"

Cons: "delay after delay after delay. And the boarding location is shameful."

Pros: "We loved watching the movie "Keanu" together on the rented iPad. The soundtrack was hard to hear on the earbuds though."

Pros: "It was short."
Cons: "The gate area was horribly crowded, extremely chaotic and hot."

Pros: "On time and short! Everything was good"
Cons: "Great"

Cons: "it was delayed for 1 hour"

Cons: "Air Canada shares a trait with many other incompetent organizers: everything is fine if nothing goes wrong, but there are no contingency plans in place in case something goes wrong. So, things get more and more delayed. Can't you predict roughly when the plane is going to land (once it is in the air!) and arrange for some gate to be open, so that we don't have to sit on the ground for 45 minutes once it has landed, for example? People who know how to organize are ordinarily capable of doing that. Furthermore, the lack of transparency is really frustrating: we just sit on the tarmac with no indication of how long we're going to be there, and the estimates of the delays are completely wrong when we're given them."

Cons: "Delays,multiple gate changes, poor waiting areas for express flights!!!"

Cons: "1h15 late"

Cons: "We got a hotel in St. Louis so we'd be plenty early for our morning flight. Got to the airport more than 2 hours early, checked in and waited. They announced over the overhead speakers that our flight was delayed due to mechanical issues. Then delayed again. Then cancelled. We were on the phone with both the airline and priceline ASAP. By "on the phone" I mean "holding for the next available representative...", which was more than an hour wait for both. The airline didn't have another flight they could fit us on until next week. We asked priceline to get us on the next available flight. We held, were disconnected, held, held more, disconnected, held more...until the day was gone. That evening they finally said they booked us on a 6:15 a.m. flight. I asked for an email confirmation and when it didn't arrive several hours later I called back. "Please hold" was the catch phrase of the day. Eventually a rep came on the line and said that we had a 6:15 a.m. flight, gave me the flight number, etc. and said the email would arrive shortly. We went to bed feeling good. We got up at 3 a.m. to get to the airport by 4 a.m. The airline didn't have anything on us. We had two hours to get this straightened out so we weren't TOO worried. "Please hold" When the priceline rep finally came on the phone she said we had reservations and the airline should let us on. Even though it was 5 a.m. now there was a long line at the airport check-in. When we got to the front of the line the guy dug deeper into his system, said he could find our reservation, but that priceline just hadn't purchased the tickets. I told this to the priceline rep on the phone. "Please hold" We watched as our flight left. We spent the day trying to get priceline to get us on a flight, but I was never able to speak to someone able to get us on a flight."

Cons: "You put me on Delta once I got to Detroit. Confusing and exhausting when you're not use to different airports and flying."

Cons: "Long time to get service."

Pros: "It left ontime and got me to where I needed to be."
Cons: "Pretzels are gross and dry. Jet Blue has much better snack choices. Overheard bins were really small on this small aircraft."

Pros: "Nothing!"
Cons: "Same as above. everything was bad. from service and communication."

Cons: "Very bad cabin pressure -- lots of ear pain."

Cons: "The movies selection is not good"

Pros: "The trip from Toronto to San Francisco was better than the San Francisco trip because the return trip was on a Boeing 747 and a much more comfortable than the Airbus."
Cons: "The Airbus red eye going to Toronto was too cramped so it was not very relaxing. The planes are not clean. I'm glad I have wipes to clean the table tray because it was messy."

Pros: "Nothing to expect more"

Cons: "The announcement about turbulence were to much. Could have been way more subtle or shorter"

Pros: "The sits were comfortable. More space between sits."

Pros: "See above"
Cons: "See above"

Pros: "Uncomfortable seat. Super old aircraft. Wasn’t even given water"
Cons: "How about a sip of water atleast?"

Cons: "A delay of 28hrs is never positive. I haven’t been able to get my United points either since I was rerouted to SFO. When claiming them the system says that I never boarded the flight to EWR and completely ignore the YYZ - SFO flight. Mediocre overall."

Cons: "At the time at the gate did not allowed me even take my caryon bag with me, the staff was so rude an in an uncivilized manner start fighting with me ,I am a sinor person got very disrespected by your staff, I would like to bring a lawsuit against UA for what you did to me ,I wish an invitator from your office contantact me to explain everything,"

Pros: "The crew were so helpful and nice"
Cons: "Only if teleportation exists"

Cons: "Crowded planes."

Cons: "At YYZ @ the wheel chair entrance, I visibly required wheel chair assistance. I approached the United INFO COUNTER and requested wheel chair assistance. She advised me to get into a long Q and after check in they will get me a wheel. chair. TSA is no greater help for your air line."

Cons: "Like everything"

Cons: "This plane was awful. I don't know how anyone who is not miniature sized could be comfortable on this plane. I am 6' 1" and ~ 200 lbs, not huge by any means, but not tiny. I legitimately could not stand up (so I had to sort of slouch walk down the aisle to find my seat at the back of the plane), then the seats themselves were so narrow that I ached terribly when seated in any position for more than acouple of minutes."

Pros: "Ok"

Pros: "Boarding was quick and efficient."
Cons: "It seemed that there was a lack of preparedness before taking off from each stop."

Pros: "Ease of checking in by phone & printing out board passes."
Cons: "That the ride was so rough. Pilot apologized & said it was just a bad nite. It was a smaller plane so that maybe made the turbulence feel worse too."

Cons: "lost our bag, crying babies, uncomfortable plane"
