Airline reviews

Pros: "Fast on the plane"
Cons: "Getting off the plane quicker"

Pros: "Courteous and professional staff"

Pros: "Flight attendants were nice based on the situations beyond their control."

Cons: "Ĺ"

Pros: "On time leaving and landing"
Cons: "Every thing went well"

Pros: "Comfortable seats, friendly staff."

Pros: "Great selection of movies to watch."
Cons: "The seat-back display screen could use some updating/improving. Also, the earbuds weren't very good."

Pros: "Nothing"

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: "had connecting flight ready"
Cons: "the plane was 5 hours late, we did not even get free internet of a coffee or a free drink in the waiting room after debarring or in the waiting room connecting was ok, they had boarding passes ready but suitcases took forever to cross customs...getting bags almost an hour"

Pros: "Ind-atl flight was absolutely amazing i couldn’t find really anything wrong with the flight besides spacing for seats"
Cons: "Spacing with seats"

Pros: "The in-flight entertainment and seats were comfortable. They gave us complimentary lunch as well, which was super helpful. I will be flying again to NYC with Delta :)"

Pros: "We were probably in the air for 30 mins; great short flight. Plane wasn’t filled so had plenty of space."

Pros: "I liked the fact that I was able to watch a movie on my phone."
Cons: "The flight was very rough at times."

Cons: "They moved me from my carefully selected seats to a row that would not recline. My flight was miserable!!!"

Pros: "Air crew was friendly and tried to get people settled as quick as they could to get back on time"
Cons: "plane was a bit late getting in so we left Tampa late fortunately my transfer gate was only a short walk from the arrival gate in Detroit so no issues catching my next flight."

Cons: "Nothing"

Pros: "Landed 45 minutes early! Allowed me to take an earlier flight Detroit to Boston which made me really happy"

Pros: "Food selection and quality were fine. I also enjoyed the entertainment options. Seat area was comfortable and spacious."
Cons: "The flight attendants were uniformly rude and nasty to passengers from start to finish. As I boarded, I asked for a piece of art to be stored in the wardrobe compartment. This was treated as an inconvenience. During and after boarding, flight attendants addressed passengers rudely when encouraging them to take their seats in a timely fashion. Later, when my seat mate politely asked a FA to repeat the food options, she asked, "Excuse me?" several times and seemed very irritated to have to repeat the choices for him. Also, near the end of the flight, a pillow was on the ground and a FA asked those seated in my row to pick it up. We responded that it wasn't ours and she said something to the effect of, "Oh yeah? So how did it get there?" (Maybe because someone else dropped it and we didn't notice?) The FAs seemed irritated to serve passengers at all. Each time they passed through for beverage or meal service, I felt like I was imposing on them. I have never witnessed anything quite like it. Makes me wonder why they were all so upset and and felt it appropriate to speak and act disrespectfully toward customers. (Delta, do you have any insights?) I hope they all got a good night's rest after that haul."

Pros: "The airline crew seems to be getting better, although I can't say that they are super helpful"
Cons: "The seats, just water offered, the bathroom, no Wifi, extremely crowded and small plane. Seriously, I don't understand what is all the money payed used for since I just heard that the crew members might be actually underpaid"

Pros: "Everything was great"
Cons: "Nothing everything was fine"

Pros: "Service, seats, food and pilot were all good."
Cons: "There ought to be a better way to go from an international flight to a connecting domestic flight. Security and Customs should be combined to expedite the process for passengers and crew members. I'm not suggesting not going through security, buy why couldn't we do it at the same place as customs? Too often Delta flights are delayed and I don't understand why Delta wouldn't do everything it could to expedite every part of the process for its crew and passengers. I went through TSA pre-check with Delta crew members. My connecting flight was delayed. We were waiting on the pilot..."

Pros: "Boarding was easy. Wifi was available and we got some snacks. Paid extra to sit in roomier coach, was worth it."
Cons: "Still pretty cramped, not the crews fault. Would've been better with the seat back screens"

Pros: "on time. easy no issues"

Pros: "Arrived sooner than expected! Nice, smooth flight despite cloudy, rainy day."
Cons: "Everything was fine."

Pros: "Short flight 35 minutes, Attendants were magnificent - friendly and focused on the customers as if they were important human beings spending hard earned cash instead of live cargo whose fares were already in the bank. This factor alone will cause me to choose Delta over others despite any small difference in price. Never waited very long in any line. Zero frustration."
Cons: "Had to pay to check a bag for the 35 min. domestic leg of my international flight which carries no baggage fee ON THE SAME AIRLINE booked at the same time. Lame."

Pros: "Pilot was hot."
Cons: "4 hour maintenance delay. Arrived at 2 am, after boarding a different plane."

Cons: "Bathroom was disgusting. Sink and toilet clogged and filled with paper"

Pros: "Everything was fine."
Cons: "No issues."

Cons: "No luggage space"

Pros: "They had a movie screen with movies available. Even though the trip was short, it was nice to have that option."

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!"

Pros: "because of the cancellation the night before I was expecting chaos. But everyone was friendly and in great spirits. No issues. Way to keep it kool!"

Cons: "Poor oversight by gate staff on limited carry-on luggage space caused departure delay, easily avoided for next time."

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

Cons: "It’s mainly all good but there are never really snacks on air canada other than pretzels (and today not even that). They are still my fave airline but they could step that up a bit!"

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."

Cons: "Everything was great"

Pros: "كل شي"

Cons: "For some reason we were forced to check our luggage (standard curry-ons) however it would completely fit to ovehead bins. Also waiting area were completely cut-off from Duty-Free shops - as soon as you passed security - no access to shopping area."

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: "Departure was orderly and staff interactions good"

Cons: "Late departure"

Pros: "Everything was perfect"

Pros: "Nothing"

Cons: "Not so bad..."

Cons: "My seat partner had a dog with her. I like dogs but it was more of a irritant and distraction, didn't seem that nice for the dog either. What happened to the pretzel/nut snacks?"

Cons: "The boarding lady on lines 3-5 was rude with several people."

Pros: "Nothing"

Cons: "The fact that my ticket said something different from my itinerary and I spent far too long at the counter to get a seat assignment."

Cons: "We were late getting into Chicago and I missed my connection to Albuquerque. I was scheduled to arrive at my destination at noon and because we were late, I didn't get home until almost midnight."

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: "I liked the boarding lines based on groups."
Cons: "Only was offered a small bag of mixed snacks and a drink."

Cons: "Received my luggage after one day"

Pros: "Was arbitrarily assigned a seat with extra legroom. No excessive turbulence; landing was smooth."
Cons: "I was among the last to board and had to place my carry-on under the seat in front because there was no room in the overhead bin. This kept me cramped the entire time despite the "preferred" seating. Soft drink servings were really skimpy."

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

Pros: "Movies!! Newer plane too."

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

Pros: "Staff mice"
Cons: "Delayed , causing delays and missed apt at destination"

Cons: "There was some dripping from the ceiling on those of us in the back of the plane. It might have been condensation from the air conditioning or air flow nozzles. In the groove of the ceiling immediately over the seats there seemed to be some dirt or mold."

Pros: "All went smoothly"

Pros: "Newer plane, tv monitors in coach class, on time departure"

Cons: "if you get in a que, then the computer goes down , your dead, AC line will be 1.5 hours to get to rebook. then you have 2 day to stay before you can get out. if you decide to go on delta because staying 2 day in hotel is more expensive than buying a new ticket ac will not refund you. Air Canada is the least flexible airline in the world relative to refund."

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

Cons: "after wetting half hour in the line they said i didn't pay for my ticket and tell me to parches a new ticket"

Pros: "Overall outrageous fees as per usual"

Pros: "Everything was handled very efficiently, and although it was a commuter jet it was more comfortable than those I've flown on domestically."

Cons: "When we checked in we were told everything was on time. When we should have been boarding, we were told there was no pilot. That took just over an hour to rectify. When we finally landed at Lauderdale, we were told there was no gate - surely they would have known this when we took off from Ottawa!? We sat waiting for at least 45 minutes before having access to the gate. Beyond frustrating when we were already late and inconvienced!"

Pros: "Flights was ontime"

Cons: "nothing"

Pros: "Wheels up to wheels down took under 20 minutes."
Cons: "I'm 6'4" and if I would've had to sit on that plane much longer I would've been quite sore. Seats are small, space is exceedingly limited. But, it was a regional jet, so this was to be expected. Nonetheless, other airlines' regional jets haven't been quite so cramped."

Pros: "The price"
Cons: "I was unable to board because I didn't see the boarding time. This should be available even if it is just an estimated time. This way if I am running late I know what time I have to be there."
