Pros: "Crew was very friendly and took good care of the passengers"
Read more about Delta
Pros: "Crew was very friendly and took good care of the passengers"
Cons: "Delta flies a lot of the CRJ planes, even on relatively longer trips. Traveling first class, the seats are a little wider than in coach and have a little more leg room, but calling it "first class" is a bit of an exaggeration. It's more like what coach used to be before the days of the flying sardine cans."
Pros: "Great service"
Cons: "Messed up my luggage in Atlanta. Gate said baggage was going to domestic. Ended up in international terminal. Added almost an hour of back and forth between terminals."
Pros: "Good experience"
Cons: "Better snacks"
Cons: "I’m skinny and 5’2” and I felt squashed. Like I was in a dollhouse. The space is too small, it’s too uncomfortable. I couldn’t take my zip front sweater off. The seats and space are not proportional to humans."
Pros: "Not much"
Cons: "Being on time. Trapped in plane for 2 hours"
Pros: "pilot was great... made the landing at key west seem easy!"
Cons: "Flight attendants seemed to really like their jobs!"
Pros: "The crew were so kind and professional"
Cons: "The flight delay was a pain"
Pros: "The seats were awful .how many can squeeze in. .horrible"
Cons: "Room to breathe, move a little"
Pros: "The website delivered everything I needed."
Cons: "More discounts for frequent users."
Pros: "We eventually got to Atlanta."
Cons: "Delta is flying a lot of commuter planes, which are pretty cramped. We usually fly first class, and the seating is essentially the same as what coach used to be. There's nothing "first class" about it. And of course, the flight was hours late."
Pros: "The crew were good."
Cons: "The flight was delayed taking off. The crew tried to make it up but it was 90 minutes late in the end - I almost missed a connection. Seats were ok."
Pros: "Crew was amazing."
Cons: "Delayed departure due to late crew arrival. Not a huge deal."
Pros: "Zee was our flight attendant and she was absolutely wonderful. Personable, attentive, and she made sure each and every person on the plane was comfortable and happy, going so far as to move solo passengers to empty rows so they could have more space. I wish she could be on every flight I take."
Pros: "I was rerouted through Detroit after it was apparent I would miss my connecting flight. The flight was good and I have no complaints."
Pros: "Not sure why this flight was delayed inbound. But it made the departure late by over 30 minutes."
Pros: "Take off on time, arrived early, pleasant flight attendant"
Cons: "Had to sit on tarmac after arriving early"
Pros: "On time, pleasant and friendly flight attendant, no unexpected issues or problems."
Cons: "Grumpy gate attendants at YUL! Could not hear the captain’s comments over the PA system. Shouldn’t the volume be checked every so often? We were offered only water or coffee, bad enough, then there was no milk or cream on board, so water or black coffee... not very impressive! And there was no entertainment so I’d rate that zero but the scale only goes as low as one star."
Pros: "It's a fast flight and boarding was quick."
Cons: "The terminal at LGA airlines is terrible."
Cons: "Customs never to hire more agents to work in the early mornings."
Pros: "On time, and pleasant flight. Flight attendants were first class: very competent."
Cons: "I slept all the way, so can’t say whether anything went wrong with the flight."
Cons: "Not much to read"
Cons: "The female flight attendant needs an attitude adjustment. She behaved as though she was doing a favor"
Pros: "Once we hit the coast we skirted down the coas of Florida which provided a spectacular view. The approach and landing at Key West airport was thrilling and absolutely perfect. We’ve flown Delta many times but this was our first but not last time to Key West."
Cons: "Nothing"
Pros: "Not applied"
Cons: "Not applied"
Pros: "We got on the plane and it went to where it was supposed to go."
Pros: "What can I say...I love Delta!"
Pros: "Once we boarded the plane, we still had to wait for the pilots to arrive and then for them to run through their pre-flight checking before we could get underway."
Cons: "The flight was delayed and the departure gate moved at the Atlanta airport 3 times to 3 different concourses before we were finally able to depart around 1 hour later than scheduled."
Pros: "Over all everything specially we got in earlier than expected"
Pros: "Kyle was our flight attendant. He was great. Attentive the whole trip and served us water and snacks."
Pros: "Crew member Lori was exceptional. Great detail to safety and customer service!"
Pros: "I got upgraded to comfort + which was great. quick flight, was even early"
Pros: "Fligth were on time"
Cons: "My flight from Montreal to Atlanta was 2:30 min Left at 6:10 arrive at 8:30 roughly Tried twice to get to my connection earlier and get 9:30 instead of 12:09 fligth to Daytona Delta was not flexible to allow me to book saying i did not have 55 min in between fligth which i had than lear n it will cost $75.00 to change the fligth - What? Very disappointed of Delta - lost 3 hrs at the airport today"
Pros: "Same as above."
Pros: "Couldn’t find a thing."
Cons: "My husband booked West Jet by phone. They spelled my name wrong on the ticket which caused hours of delays tryng to check in...ultimately leading to our missing the flight. The time spent was around 6 hours....4 of them the were on one continuous phone call where we were bumped back and forth between West Jet and Delta. The problem was never fixed and we haven’t flown home yet. We have new flights booked on Delta but only because Delta took pity....West Jet does no refunds or reticketing. If flights are missed you're out on of luck!"
Pros: "That I was able to sit next to my husband"
Cons: "Everything else."
Cons: "Nothing"
Pros: "The crew boarded us efficiently, and got us off the ground on time, but the boarding experience is not pleasant."
Cons: "The food selections are limited. The crew ran out of popular items in the economy cabin. The personal seat lighting on the B-767 never quite worked. I eventually gave up on it. The overhead bins were too small for many roller boards, which caused some passengers to be perplexed. Delta should offer some inducements to encourage passengers to gate check bags."
Pros: "Flight was delayed by 2+ hours, Delta (running the flight for westjet) sent 1 email about the flight being delayed to 4:45 which was inconsistent with the gate signage and agent who said 3:45, flight ended up leaving at 5:45PM. No reasons were provided beyond the incoming flight from LGA hadn't come in. Why hadn't it come in? When could we expect to leave YUL? No answers."
Pros: "Delta automatically rebooked our flight due to delays. We were rebooked on Air Canada"
Cons: "Plane kinda of old. Just cookies and coffee"
Pros: "The in flight entertainment and the pilot being informative about what was going wrong at the Atlanta airport."
Cons: "The insane process that followed the flight of rebooking - it would have been VERY HELPFUL to have access to the inflight internet so that I could have rebooked my missed connection before we landed in the ATL airport where it was past midnight and there were hardly any staff available for us to talk to and the lines to speak to anyone took literal HOURS to get through."
Cons: "Seats are very small."
Pros: "Got grounded for five hours stuck on the plane."
Pros: "Nothing to like about this leg"
Cons: "The cramped real cramped space, shame on the US Poor service Delta should be ashamed of itself for this kind of poor cattle transport"
Pros: "Staff hospitality"
Cons: "Deboarding delay, seems typical"
Cons: "lack of carry on luggage space. very tight. gate agents did not care about the customers. I had to stick my bag under the seat and only half would fit so my feet did not fit with my bag. it was a back pack. I do not prefer checking luggage since I've had so many bad experiences."
Cons: "2 of my 4 bags, which I checked in, were broken during my travel."
Pros: "Both the crew in the plane and the groundcrew were helpful. Particularly the people in Key West, in terms of finding our luggage and helping us get a taxi."
Cons: "Offer offer healthier food choices, and larger amounts for beverages, particularly water."
Pros: "The landing experience."
Cons: "The organization of serving meals."
Pros: "Crew most helpful."
Cons: "Always like to travel with WestJet."
Pros: "Crew was good"
Cons: "Montreal airport was awful"
Pros: "not much, not even close to the service and comfort I am used to flying."
Cons: "Keep planes in working order"
Cons: "Service is awful, they cancelled a flight and they reserved the wrong flight so we couldn't get to the destination. Had to change airline and extend our flight by 9 hours with our baby. Horrrrrrible experience. Staff didn't seem to care. They put everything on their supervisor and she tried to help"
Cons: "Access to the internet and in film movies on my ipad was not functioning! Made for a longer flight not being able to watch movies."
Cons: "After landing, we were waiting on the tarmac for sometime and I needed to use the restroom I was an allowed to do so. It would’ve taken me a short short time. I went to The rear of the plane to use the restroom and was told to get in my seat."
Pros: "Getting home"
Cons: "Leaving Montreal"
Cons: "Small plane"
Pros: "I slept throughout the flight"
Pros: "I liked the price for my flight however I booked using my AirMiles."
Cons: "I have travel with WestJet many times is the past and had nothing but good to say. This was my first time using WestJet Encore and was totally shocked and disappointed. The flight crew i found to be very rude with and had an attitude. The biggest shock was the greetings and all announcements were in English accept the safety rules where the pre-recorded tape was played. If asked about the return flight from Halifax to Montreal, one word to describe it "disaster". I was totally turned off with WestJet. I will for sure continue using Porter as I was always pleased with there service. As they say "you get what you pay for"."
Pros: "Westjet team is fast, nice and solve issues in one call. I have had very good experiences with westjet! Thank you!"
Cons: "Today in Montreal during boarding the lady coordinating did not give priority to people with children. We were at leastthree families - we were all upset with the situation. However as I have had very good experiences with west jet I consider this an isolated issue."
Pros: "Friendly crew"
Cons: "No entertainment and bag charge."
Pros: "We were late getting to YUL because of traffic, and a West Jet employee went above and beyond to make sure we made it on our flight even though we missed the cut-off time."
Cons: "No entertainment on the return flights Yeg/Yul !! Makes for a long flight."
Cons: "They tried for force us to pay for a different ticket because we had gotten a cheap initial ticket!"
Pros: "The service of the crew was fantastic."
Cons: "No food included just water and Coke."
Pros: "Very smooth flight!"
Cons: "None. All is great!"
Pros: "everything"
Pros: "I love flying in a smaller plane. They are usually not full in the morning and so it gave me a lot of space to relax and enjoy the flight from montreal to toronto. The crew was really nice and smilling and they made sure that my pet and I had everything we needed."
Cons: "The seats are pretty thin and uncomfortable. There is no wifi or television on board."
Cons: "Delays"
Cons: "Staff was rude and lazy."
Cons: "avoid the westjet encore flights. planes are small and noisy. if you sit next to a window it’s impossible to comfortably put both feet on the ground. if you pay for plus seating on an encore flight you’re basically paying to get on and off first. there’s no extra room and would be more fairly priced at $10."
Pros: "The flight comes into Vancouver at a very good time."
Pros: "The flight attendants were very nice. Especially « Big John », he was very funny."
Pros: "Very friendly"
Cons: "We were delayed 45 minutes without reason, we asked to have our flights switched as we were nervous of missing our connecting flight and were told we could not switch. While we were waiting on the runway for over an hour I asked our flight attendant to check on the status of our connecting flight and she basically told us to hope for the best and that we would have to deal with it when we arrived in Toronto"
Pros: "Boarding agents were welcoming and helpful. They offer to take an earlier flight. Check-in process fast and easy. They delayed the connection in Toronto, so We did not miss our flight."
Cons: "We had to wait about 2 hours in the plane before take off and 30 min. after landing because of weather and a lack of efficient communication. That was a very frustrating and exhausting flight. Not enough space and on westjet connect on board."
Pros: "The seats were vinyl, not fabric - I prefer vinyl. It feels 'cleaner'."
Cons: "1.I did not like the flight crew announcing how great they (the crew) were at the start of announcements before take-off ---- If you are great, don't tell us, act like it - I found both crew members hardly engaging, one was sullen. 2. PA system was a little hard to understand anyway. Crew member should have put volume up and made sure was loud enough , but just seemed like wanted to use a 'cute' half french/half english accent to speak in. 3. Also this flight 3535 on Dec 21 Mtl- Toronto made me nervous although I fly often. Most nervous I have been because pilot took time to gain altitude after take off, and when landing had to accelerate then decelerate a number of times. Landing was (with 2 km/hr winds i.e. not much wind) almost on one wheel. 4. Food does not have to be so cheap e.g. sweet snack bar? Please bring back an assortment of nuts as they are at least nutritious. Thank you for reading."
Pros: "Nothing"
Cons: "I didn’t book the flight. Was just checking and got the confirmation of booking. Called customer service and they cancelled the booking. Question is why there is no confirmation button and how continue button can confirm the booking. Kayak need to check and advise."
Pros: "Staff was great"
Cons: "The 4hour delay on the one hour flight"
Pros: "Fantastic flight!"
Cons: "Being stopped at every connection for screening. No communication about why. Nearly missing the connection due to the screenings. Being held in holding because it was being confirmed that my bag would make it on my next flight and then once confirmed it never made it anyways!!! Unprofessional and poorly executed all the way through."
Pros: "The staff are always super friendly on Westjet."
Cons: "The entertainment system is terrible. It does not work on my laptop and they sell out of ipads quickly."
Pros: "The crew."
Cons: "Everything else. Flight was delayed by over an hour, seats are slippery and SO uncomfortable. No food, no entertainment (flight was only an hour)."
Pros: "I liked that the inside of the plane was new, bright, and modern. Really great craft."
Cons: "It was a propeller plane and it doesn’t say that when you book. And they only gave water and pretzels. Nothing else. No soda, no coffee, etc. I was interested in purchasing a snack on board and the stewardess said they don’t sell on the flight because it was so short (40 min flight time.) lgehixh I could understand, but AirCanda offered a variety of snacks and drinks during the same 40 minute flight, so not sure what’s going on."
Pros: "It was a comfortable experience, the flight crew were attentive and friendly."
Cons: "The lack of space beneath the seat in front of me can be frustrating, especially when one is required to push their small bag underneath it."
Pros: "Quick boarding and quick to disembark."
Cons: "tiny! you get what you pay for with a turbo prop."
Cons: "You should hire agents who don't lie to passengers. That's not a good reputation 4 the company. Have an office for the baggages where passengers can address their issues."
Pros: "The flight was on time"
Pros: "That we didn't crash."
Cons: "Two hour delay, disinterested CSA when checking in, clued-out flight attendant, GSA's didn't know how to gate check luggage. Will try to never fly another WestJet flight again!"
Pros: "Flight was on time."
Cons: "Seating was very cramped, uncomfortable."
Pros: "I liked that the pre-ordered food was given at the beginning of the flight."
Pros: "Crew was great. Flight was on time."
Cons: "This older plane had tiny seats in the seat backs. My phone screen was bigger. Thought we might get a meal on a flight of this length and at this time of day."
Pros: "Boarding was quick and efficient, Crew was nice, competent and friendly. The Flight was quick and uneventful."
Cons: "1. Unexpected 25$ checked baggage fee 2.No meal: They only served drinks, pretzels and hard cookies. Extra food needed to be paid for. 3.Older aircraft so no entertainment options other than TV and Movies. (no way to start, pause or end any movies or programs."
Pros: "Nice and professional service."
Cons: "Having to pay for my checked-in bag."
Pros: "Customer focus and service"
Cons: "Nothing"
Pros: "Friendly staff"
Cons: "All flights boarded late, they ran out of food for purchase on long flights and the seats are uncomfortable."
Pros: "Montreal to Toronto the crew and staff was great and in a good mood and very pleasant"
Pros: "all the service was very good to us"
Pros: "In-flight service. Complimentary wine & beer. Flight attendants very friendly."
Cons: "There were several gate changes and delays. My boarding pass gate information did not mirror the gate information on the terminal screen. When I asked the AA employee at the counter to verify the departure gate, he was extremely rude. I understand gate changes and flight delays may be expected, but it made for an awful experience."
Pros: "Nothing"
Cons: "Everything"
Cons: "That particular plane seemed old and interior worn."
Pros: "Internet"
Cons: "Turbulence"
Cons: "I was asked to move from the front of the plane to the second to last row without a thank you or any kind of appreciation..."
Pros: "Our flight attendant was very polite and with a great attitude."
Cons: "The pilot arrived late because he went for a Tim Horton's coffee (I know that because I was in first row and I heard the flight attendants talking about that). Then, after he finally arrived with a tray full of coffees, there was an issue with the jet's computer and had to reset it and we had to wait even more. When we finally arrived, our Gate was taken by other plane already and we had to wait (more) for the first one to be available for us. Then, when we finally got our Gate, there was another issue, now with the "finger". They weren't able to move it and connect it to the plane to get off of it. So we had to wait AGAIN. And finally as soon as we got off the plane, they were supposed to give us our carry ons on the aisle (Because it was a small plane CR700) , but again, we had to wait almost 10 minutes so that they could send the luggage... To make things worse, I had a first class ticket and I couldn't get the perks of it at the airport. Because they said I wasn't flying in an international flight. Come on?! Canada->USA->Mexico is not International??? You lost me AA."
Pros: "Nothing"
Cons: "Had to change our plans, and AA wouldn't give us a refund. We never got on the plane but had to pay for the tickets anyway. I'll never fly AA again."
Cons: "There was no place to charge my electronics"
Cons: "Communicating rules such as not going through the business class to loop around to the other aisle of the coach class is definitely acceptable however the tone in communicating this should never sound condescending and patronizing, esp over the PA. Flight staff shld refine her communication skills."
Pros: "I like nothing!!!!!"

Pros: "Kind crew"

Pros: "Nothing"
Cons: "Flight was late and caused me to miss my flight to Dallas."
Pros: "First class seating comfort and service. Even my flight in the main cabin was relatively comfortable, but I'm a smaller stature person so... On time promise kept every flight."
Cons: "Extreme noise from the plane at certain times (mostly takeoff which can't be helped, I guess) Sitting in the first row of first class you get the light from the flight attendant kitchen area right in your face (Seat 1A-3A specifically)"
Pros: "Good boarding and on time departure."
Cons: "Very uncomfortable seats and spacement between the seats too small and you feel very cramped specially when the person in front of you reclines his seat you can hardly move."

Cons: "I was cramped in Seat B."
Pros: "The crew was accommodating"
Cons: "The crew was pleasant. No water served due to turbulence"

Pros: "Friendly staff"
Cons: "Food was terrible and the seats tight"

Pros: "First time flyer with American airlines and the service was impeccable"
Cons: "Nothing to dislike"
Pros: "The crew was great! They did big effort to speak in Spanish! And also they are kind in every thing!"
Pros: "Very dirty and unconfortable Airport Environment."
Cons: "Combination of Business Class and Economy Class ticket sold by British Airways, although offered as Business Class. Hat a lot of Trouble with British Airways."
Pros: "The actual crew on the plane were great"
Cons: "On my trip to Atlanta from new York the gate staff were horrible. Nasty attitudes and forced me to check in a bag that is made and approved by airlines to be considered a carry-on making me miss my 6 am flight to then book me on a 930am flight that was delayed for about an hour. I've never experienced this with any other airline before. Very disappointed"
Pros: "Nothing"
Cons: "Late taking off and arriving. Once we landed it took 15 minutes to locate someone to bring the ramp out to the plane. Just incompetence on part of American Airlines."
Pros: "Having flown long haul with American numerous times, this time I was pleasantly surprised by several things. Firstly, the brand new plane with excellent in-seat entertainment choices, power points at every seat, more comfortable chairs with better head rests and even window dimmers vs. window shades, allowing you to look outside the whole flight. Secondly, the food was much improved...definitely better quality and tastier than typical airline food. And thirdly, better service from flight attendants who actually smiled. Keep up the good work. This represents a real step change."
Pros: "The boarding process was easy and the seats were extra comfortable"
Cons: "Nothing"
Pros: "Good seat back entertainment system. Plenty of movies I wanted to watch. Good to have an AC power outlet, too, to keep my phone charged."
Cons: "Charging more for some seats is a crappy business practice. Never enough room. Warmer than I'd like. Guy behind me kept stretching out his legs so much that he'd hit my feet unless I also stretched out."
Pros: "On time, smooth check in, great customer service at the gate and on board."
Cons: "Snacks should improve"
Pros: "Was on time, flight attendants very nice and professional"
Cons: "flight was overbooked good thing people volunteered to give up seats"
Pros: "Crew was very professional"
Cons: "My flight was delayed 5 hours"
Pros: "Our flight was cancelled"
Cons: "Our flight was cancelled And rescheduled and we were not notified. We missed our flight. The next flight was the following day. We missed a day of vacation and $500 a day hotel fees. We felt we should be reimbursed for our flight but the person we talked to wasn't too helpful."
Cons: "My direct flight was cancelled. My rescheduleday flight was delayed and I missed my connection and had to spend the night in the airport. My 2 1/2 hour flight turned into a 16 hour trip."
