Cons: "See above"

Cons: "Got in early"

Pros: "Nothing"
Cons: "Felt agents held me back at the check-in counter resulting in me missing my initial flight and voiding my complete routing. Had to fly on a flight 7hrs after my booked flight because Delta had no other option (very untrue as there were other airlines flying to my final destination. Delta just didn't bother providing good customer service"

Pros: "Seats were comfortable ... enough. Boarding process, once underway allowed me to get overhead bin and stash my other luggage in the seat below me. Flight wasn't overly booked (85-95%) so there appeared to be room for others to stretch out. Now about that crying kid..."
Cons: "Ugh. Weather delays. The flight was scheduled to board about 7P but it arrived late and they had to not only unload the self-loading cargo, but clean up afterwards. Would be nice to get a better estimate as to how long it would take to board so that I could hang out in the lounge. In addition, departure from JFK was delayed as well, either we missed the IFR window or got stuck behind some traffic and I fell asleep on the plane only to wake up what seemed an hour later just getting ready to hit V1. No upgrade."

Cons: "Force me to take a bad seat"

Pros: "We were not happy with our flight my flight got cancelled 3 times I miss work they need to reimburse us and also reimburses the hotel cuz we had to stay at a hotel because they cancelled our flight three times and then our flight that we went out on Monday was late because of a flight attendant arriving late to the hotel to the airport"

Pros: "I didn't get a chance to get the gentleman's name at the gate, but he was able to get me on the earlier flight (since I had NO luggage and only 1 carry on that fit under my seat) and didn't charge me the stupid fee for filling a seat that was empty when I was giving up a seat on a later flight that would accommodate those who missed this earlier flight. Nice to see kindness in an industry that seizes fees on every opportunity."

Pros: "The temp"
Cons: "It was too hot."

Pros: "Maintained high standards of service despite massive delay."
Cons: "Boarding and departure was messy because of the delay"

Pros: "We'd paid extra for main cabin so hot to choose seats and got in flight entertainment.. Staff were friendly."
Cons: "No free wifi."

Pros: "The entertainment options and noticing the little touches that Delta is making to improve the brand and experience."
Cons: "Seems like there are legacy "attitude" issues with the crew. I sat on the aisle yesterday, and SEVERAL times I was bumped, quite rudely, by passing crew. In one instance, as they passed to pick up trash, they took two of my three items. They started walking on, and I tapped them as they passed to pick up the third. She brusquely turned and said: don't touch me to get my attention. No please; quite rude, and unnecessary."

Pros: "The boarding was efficient"
Cons: "Three hour departure delay. No explanation given. No apology."

Pros: "Entertainment system"
Cons: "Crew lacked any customer centricity, service was poor"

Cons: "Boarding process was horrible, it was first class, priority, zone 1 and then all other zone. There was no order. Flight was delayed. Had a 3 hour delay on the tarmac!"

Cons: "Be on time!"

Pros: "Good connections, short layover but long enough."

Pros: "Crew."

Pros: "Nice new 737 max aircraft"

Pros: "Horrible check in"
Cons: "Rude staff"

Pros: "We took off on time and landed a little early. Crew were very nice. I couldn’t judge the entertainment as I didn’t have iPad with me to connect to the wi-fi and watch movie. Plenty of snacks. Worth the cost of the flight."

Cons: "Food not so great Also wanted music. Was none"

Pros: "Need more leg room"

Pros: "Good price for long haul destination. Efficient check-in and boarding process. Decent leg room for a budget airline."
Cons: "Food choice a bit limited - especially the free offering. In-flight entertainment is only available from the WestJet app to view on your own device - you need to know this before you board - otherwise you are not able to access any of the movies etc."

Pros: "Had seats in row six -- plus there was room for both our carry-ons!"
Cons: "Flight was delayed taking off from Winnipeg 90 minutes with no explanation given. Made us late getting to Saskatoon and missed our daughter's scheduled ride to pick up our two cars as a result. Had to pay an extra two hours parking at airport, etc etc etc."

Pros: "Joesph air host was amazing! Took care of numerous people with kindness & professionalism on our morning fright from Toronto to Vegas!"
Cons: "Lots of kids on the flight. Parents did a great job coupled with the staff. I very grateful! I needed a nap ! Iol"

Pros: "The flight was on time."

Cons: "Tiny chairs"

Pros: "So poorly organized at boarding ! Staff on the ground that where lazy ! On board staff where lazy ! Waiting for luggage took over 40 mins. Horrible ! Good thing I've had other flights that where much better."

Pros: "West Jet just runs a relaxed yet professional airline. They are just more laid back and accommodating. You can use any bathroom on the plane as well which is huge on those rare times you need to use it. They are funny and chatty and seem to enjoy working together which all translates to a less rushed and relaxed experience for us the passenger. I really can’t complain....I had an entire row to myself....the best you can hope for, when riding on a plain for hours that’s like winning the lottery!"
Cons: "No complaints for sure"

Cons: "I was in row 2 and they did not have the food item I wanted. Seriously?"

Cons: "The crew on the plain was extremely rude!!! Very very dissapointed!"

Pros: "West Jet never disappoints..."

Cons: "having to walk outside the plane in the snow to get on the bus and vise versa. it was cold and I got a bad cold...."

Pros: "WestJet was great. I had assistance this flight and they took great care of me"
Cons: "Totally full flight so squished in my seat"

Cons: "Lack of attention from aeromexico in customs to ensure making the connection. Sevice is a joke."

Pros: "The reservation was quick and effective"

Pros: "Crew was great"
Cons: "Who decided that seats should be shaped that way? Always gives me a backache."

Pros: "Lots of leg room and liked the screens for each seat even though I could not listen to what was playing on it."

Cons: "All good"

Pros: "Personable and professional staff. Great service"

Cons: "I was really tired. Long line getting into the USA section. Argh. Let's just say I was grumpy and wanted to get home. Staff wss really nice."

Cons: "So far better than most of the US airline."

Cons: "No choice for seating - my husband and I were seated separately"

Pros: "Really great attendants. Friendly and humorous."
Cons: "They took the tablets pretty early it felt. 45 minutes before we landed. But other than that, great experience!"

Pros: "As usual, the gate and air crew were extremely helpful and efficient. I love that the flight attendants almost always have a great sense of humour. This helps put everyone at ease and in a good mood for take-off. The flight was right on time."
Cons: "We gate-checked our baggage on the first leg of the flight and didn't quite understand why we had to take it off and back on again for this flight when it was on the same plane. There wasn't much legroom; and when the rather thoughtless guy in front of me reclined his seat fully, I could barely move. Luckily, it was a short flight."

Pros: "Best WestJet flight ever!"
Cons: "No issues."

Cons: "Delayed for almost 2 hours"

Pros: "Reaching my destination"
Cons: "Wish the emails/alerts came sooner. I waz always in transit when i was told my flights had been delayed or cancelled. I wont blame people for weather but it was the most annoying trip i have yet to take. I dont mind dissapointment but please dont waste my time."

Pros: "same as above."
Cons: "same as above."

Pros: "Everything was okay"
Cons: "My boarding was no so good. However all went well."

Pros: "Comfortable flight, entertaining stewardess, on time arrival and departure, good service."

Pros: "A staff of 2 attendants on a crowded A 321 is minimal, not optimal"

Pros: "It's a direct flight."
Cons: "Everything - the plane was last updated in 1989 (you can still see where the cathode ray screens were bolted to the central overhead bins), the entertainment is laughable, several didn't work - passengers were given choice of putting up with that or getting off flight. A flight to endure, not enjoy"

Pros: "The seat was fine for economy"
Cons: "You should offer free wifi! Air Canada should lead the way and be above the rest!"

Cons: "No good"

Cons: "No snacks unless you are willing to pay more than 10 dollars lol"

Pros: "short pleasant experience"
Cons: "baggage check is always complicated .they make a big deal over small items"

Pros: "Very good flight experience"
Cons: "good planes, good services"

Pros: "Got to Newark fast luggage was off plane very quickly"
Cons: "Older plane no body at gate to drive jetway gaving us sit out on tarmac"

Pros: "MIGHT give me a refund, and not WILL give me a refund"
Cons: "Service personnel at Air Canada were very helpful and re-booked me several times and when none of those flights left, they said they would refer me to refund department."

Pros: "Plane was nice Crew was great"

Pros: "Good leg room. Staff friendly and helpful. Really great flight."

Pros: "Boarding process"
Cons: "Cabin Crew did not provide water to hydrate the passengers but, one time on the flight from Toronto to San Francisco."

Pros: "Everything I'll do the same next trip!!"
Cons: "No complaints!!"

Cons: "Talking, crying 6 yr old next to me."

Pros: "Long slow lines. Insufficient signage for US Global Entry. Too few and slow US Customs. Largest plane ever flown to Florida from Northeast."

Pros: "787-9 Full Flat business class"

Pros: "Nice selection of media. 767-300 is comfortable."
Cons: "Late boarding due to plane's turnaround issues. Unusually long delays at baggage claim...may have been lack of coordination on part of the airport."

Cons: "Late departure"

Pros: "I was able to change my seat from a middle to a window. I also had an open seat next to me so I was not squeezed in. The person at the desk in Toronto was very pleasant and helpful."

Pros: "Flight attendants were rude had to check my carry on since there was no room overhead cabin. This happens frequently with Air Canada"

Pros: "Nothing"

Cons: "Not so bad..."

Pros: "Efficient boarding"
Cons: "The headphone jack on my seat was broken which for a 5.5 hour flight is quite difficult. The only compensation the air flight attendant offered was a glass of wine,which I couldn't drink due to being on medication. I had purchased 3 meals and 2 snacks so she could have comped one of them. This is the second time I experienced this on Air Canada with little to no appropriate service recovery. I had my iPad~an offer of free wii fii would have also been an option"

Pros: "Everything was good, that day was to much therbulans. Thank you air Canada"

Cons: "Air Canada staff appear to wear their job dissatisfaction on their sleeves. They don't smile enough and often when they do its to each other like there's an inside joke we don't know about."

Pros: "none"

Cons: "Uncomfortable, had to sit sideways since my seat didn't recline and the passenger in front on me reclined into my lap. Stewardess did nothing to help, chose to ignore me and went in the back to knit.."

Pros: "on time, boarded quickly"

Pros: "Having empty seat next to me made for comfortable trip"
Cons: "Broken headphone jack made trip feel very long and boring because couldn't watch TV."

Pros: "Airlines keep the cabin too cold. On the domestic of the travel leg blankets were for additional pay which is crazy - I understand about meals, but blankets are required only because the conditions offered by the airline are uncomfortable. One luggage was lost, but that is now almost part of travel."

Pros: "Was not delayed"

Cons: "Received my luggage after one day"

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: "The fight had intercom problems and that delayed us for 5+ hours with no decision as to the resolution. We finally got home at 4 AM ...."

Pros: "The pilot set an expectation of an early arrival (30 min) that was not met."

Pros: "The fact that the plane landed safely"
Cons: "The service was horrible. They kept changing boarding gates on us. Luggage didn't arrive. A little delay. The service was poor as well"

Pros: "Great airline. Highly recommend them"

Cons: "Squeezed in like sardines. Nickled and dimed at every turn."

Pros: "The crew members tried their best in the unfortunate circumstance and the choices of movies was okay but it was better than nothing."
Cons: "I chose to fly directly to save time, and I spent the extra $100 for choosing this option over flights with a layover. I ended up waiting an additional 2 and a half hours before the flight took off -- in this time I also requested for a blanket since the air craft got cold. There was an extra charge for this as well. It is ridiculous considering, the purpose of my flight choice was to ensure that I saved time and in return I paid for the convenience, ironically it didn't work out that way. There was no form of compensation."

Pros: "Movies!! Newer plane too."

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."

Cons: "No variety in menu for a long time (business class)"

Pros: "Had extra legroom but paid for it"

Pros: "Asian flavored snack mix was way better than stale peanuts. Check in, gate, and attendant staff were A+."

Pros: "Once, on board everything went smoothly"
Cons: "Not being made aware of the real departure time ahead of time."

Pros: "The complimentary snack"
Cons: "That my seats were not together"

Pros: "Movie choices"
Cons: "Terrible boarding and awful transfer connection at the Toronto airport."

Pros: "Everything was as expected"

Cons: "great service & was on time & we landed early too!"

Pros: "I was able to watch Monday Night Football on Directv."

Pros: "Comfortable and on time"

Cons: "My suitcase was ruined in transit to Kansas City. The help desk basically asked me to leave my bag behind for three weeks to see if they can fix it. They had no means of looking after the contents. Was I suppose to carry my content???This was ever so frustrating since the suitcase was brand new. Then the lady told me that my warranty on the bag will cover the damage. It was obvious she was not willing to help and did not have a clue what she was doing thus I just logged the complaint and had by suitcase sorted out the San Francisco Airport. They were very helpful."

Pros: "After all these years, still love United!"
Cons: "Loved everything!"

Cons: "The stewardess was very hard to understand in English."

Pros: "No Lufthansa?!"
Cons: "No Lufthansa?!"

Pros: "comfortable seating."
Cons: "Having to pay for one piece of luggage Plus on small plane announcement should be made to watch heads when getting out of seat. I got up from window seat and smacked my head hard on overhead bulkhead. Got a big sore bump from that."

Pros: "On time"

Cons: "Almost ruined my trip and lost a day of vacation"

Pros: "Everything"
Cons: "None"

Cons: "Were held up by TSA in San Francisco because we were not given receipt for our dog who traveled with us. (We had a 2 hour layover in SF and took dog outside the security area for relief). Then the ticket counter in SF was understaffed and it took a long time to get the receipt printed (Once at the counter the agent was very helpful, efficient and quick). Should have a pet area inside the security of airports, like Palm Springs does."

Cons: "Good"

Cons: "Kayak suckssssssssss"

Pros: "The price...for once, a weekend to SF was reasonable!"

Pros: "N/A"

Pros: "The stewardesses wee attentive. Liked my other passengers around me."
