Cons: "We arrived around 39 minutes early and the whole process was very smooth"
Read more about Delta
Cons: "We arrived around 39 minutes early and the whole process was very smooth"
Pros: "Not one of my good experiences with Delta. Two hours delay in the flight"
Cons: "Information on the flight delay as communication was. at least very poor. Also A 220 was ok but First Class was so so"
Pros: "There were a few hiccups with the overall flight process, but the crew was very friendly and informed everyone in a timely manner of the situation. There were also good snacks. Also, flexible baggage policy, which was great."
Cons: "The boarding situation is odd and less organized or structured than any of the other airlines I've flown with."
Cons: "No AC for an hour before takeoff - very uncomfortable. Audio for tv did not work."
Cons: "Flight was delayed a bit due to a couple passenger booking/misc issues. 1st class didn’t get gate bevfood service. Oven was busted so my meal wasn’t available. Entertainment console had all channels functional except — not really an issue I just really wanted to have ESPN playing in the background"
Pros: "Crew was nice and welcoming"
Cons: "Well, if our plane had been leaving on time it would've been superb."
Pros: "Jeff was our flight attendant in first class. He is an excellent flight attendant. He has an amazing attitude and his manner made us feel as if we had been friends with him for years."
Cons: "Passengers who pay retail for first class on domestic flights should get access to the Delta lounges even without the AE card. Other airlines do this, and we have come to expect it."
Cons: "My flight from Chicago was two hours late and that's why I missed the flight from Atlanta to Buenos Aires. No one helped and did not know that the flight was delayed and I had to find a place to sleep. I'm not satisfied with the experience and I have not yet arrived in Argentina because of the whole"
Pros: "Excellent hospitality I asked for a cup of coffee at an odd time, the attendant went out of his way to brew fresh pot and served me, instead of just saying "Sorry sir, we don't have any coffee at this time....""
Pros: "N/A"
Cons: "Chinese Eastern did not try to help and solve my problem."
Pros: "Flight was cancelled after multiple delays & I changed to United."
Cons: "Stop delaying & canceling flights, especially last minute"
Pros: "Really easy boarding and flight. Great in flight entertainment options."
Cons: "Because of 12 hr between original flight and this flight, we drive"
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Pros: "Crew was great."
Cons: "Plane was about 1000 years old and I don’t think I’ve sat in a more uncomfortable seat."
Cons: "I was apparently "flagged" by British Airways for extra security checks. As I understood it in London, I was randomly selected for this security check. This then apparently meant that I was to be flagged for all subsequent flights. This meant that in Chicago, after going through two other security checks that day (Zurich and London) and completing customs, I had to engage in a full Homeland security check. This involved removing protective covers from my laptop and phone that were hard to get off (not meant to be taken off regularly) and a full body search that I did not have to do in London. After many hours of traveling, this was very a frustrating experience."
Pros: "Flight crew was great. The plane was half full, so the attendants allowed us to move."
Cons: "Terrible landing in Charlotte. The plane was rattling and had an annoying whistle."
Cons: "British Airways/American Airlines lost/delayed luggage again! Then send an email in the middle of night with a link to schedule home delivery of the luggage that was valid for 4 hours only. It is clearly an attempt to cheat out of their responsibility of home delivery of the luggage that was delayed the second time. Poor, poor service by American Airlines."
Cons: "It was not clear that I needed a different 6 letter code to checkin using the AA website. I finally got frustrated and called AA only to find out the code was different. The codes should have been the same or you should have referenced it on the website when I tried to check in"
Cons: "Flight was delayed for more than 4 hours with little communication from staff as to why, gate was changed to a gate across the airport."
Pros: "Crew was amazing."
Cons: "Wish the wifi was faster; not that much on IFE. Food was good but not great."
Pros: "The boarding and deplaning were well organized and handled very professionally"
Cons: "I had an aisle seat that was hard as a rock. The cabin crew repeatedly slammed into my shoulder with their hips and carts and never once excused themselves or asked if I was okay. The PA was muddy and difficult (near impossible) to understand."
Pros: "He united crew in Chicago were awesome, they got us on a much quicker connection home! Great customer service"
Pros: "United Terminal in Chicago had limited seating and dining options. Flight was overbooked, but boarded quickly."
Cons: "Baggage claim at IAH took 45 minutes. Incorrect claim area was indicated for first 25 minutes, with over 200 people crowded around 1 claim area with 12 others open. Finally switched and bags took another 20 minutes. Baggage claim always takes over 30 minutes at this airport. Subway is rickety and outdated."
Pros: "Absolutely nothing!"
Cons: "On this segment of flights it was an absolute joke. Assigned a center seat along with other 1K members and stuck in the back of the bus. Flight was hot, late and then once to Houston could not get off the plane as there was nobody there to meet us. Priority bags all came off the caraosel last."
Pros: "The flight was on time."
Cons: "I think that going stingy with customers on a flight regarding food is disappointing. It’s the first time in my life that I travel and the airline doesn’t not provide food in the overall cost!, and charging for entertainment:speechless! And the seats, well uncomfortable would be a nice word to describe them.No United again!"
Cons: "Why is United charging for inflight tv and movies? Ridiculous"
Pros: "Nothing!"
Cons: "Flight was delayed for HOURS! Would havepreferred to change flights. I had just flown from Italy, stuck in Chicago for hours, get on the plane, would have to pay for any food? That’s not right. Won’t fly United again."
Pros: "Nothing positive to report...NOTHING!! Flight was three hours late leaving. No pilot then no device to move the plane away from the terminal"
Cons: "Worse travel day of my life. I'll never fly Lufthansa again and never go thru Frankfort again. Lost luggage both ways. Awful experience!!"
Pros: "Crew was great. Food was tasty (croissant, etc), great touch and really appreciated the service and attitude of the crew especially the lady in first class. She could not do enough to please the passengers. A+"
Cons: "Took a long time for the ramp crew to get ramp to plane door (3-4 minutes) ??? C-"
Cons: "The flight was super delayed because Frontier was sharing a gate with another airline..."
Pros: "Crew was super nice"
Cons: "Delayed 3 hours, boarded and was told would be another 30minutes because of mechanical issues."
Pros: "Fast boarding and that's the only good quality. No refreshments or snacks offered without a price tag included. Seats don't recline. Uncomfortable hard seats without any head rests for Support. Small tray tables that won't hold a laptop or drink."
Cons: "It's been 45+ minutes after landing that we have been stuck on the runway unable to dock the plane due to some delays. How Terrible is it that the pilot gets on the radio to say he has no updates or much information to give! People are antsy, children crying and this delays all passengers with other accommodations. Seems like there's no communication or organization from Frontier at all!!'"
Pros: "Easy"
Cons: "Shared my row with 500lb people and though two rows ahead of me had two empty seats I couldn't move to be comfortable. This beast of a woman couldn't put her arm rest down and therefore her body was smashing mine the whole time. It was disgusting."
Pros: "The crew had a great attitude and was able to make us laugh despite the fact that we were leaving late."
Cons: "The plane was dirty- there was balled up gum wrappers, food wrappers, and bites of food on the airplane floor. To make maters worse the carpet was already stained in multiple spots. My tray table also was dirty with sticky soda that had spilled on a prior flight. I was quite disgusted by the condition of the plane."
Pros: "Crew was nice"
Cons: "Charging passengers extra for carryon bags and certain seats is ridiculous. The majority of the plane was empty which means you could have just moved to a different seat (that would have cost $11 more) once everyone boarded the plane. There is really no purpose behind the additional charges and negatively impacts the experience."
Cons: "On flight from Tampa to Chicago nobody charged me for carry on,and on a way back they charged me 60 dollars,so,this is the last time to travel with Frontier"
Pros: "The cost of the flight was very cheap, which is nice when you are flying somewhere far like Chicago to California (usually one way can be over $200). The boarding process and crew were all very nice."
Cons: "You get what you pay for. The seats aren't the most comfortable and you don't have the best legroom. Also, pack light so you can fit everything under the seat and avoid extra costs. Good for some travelers, but not for everyone."
Pros: "They only had one plane, it was weather delayed at its previous airport, then it ariver with mechanical problems. Customer service promised me the flight would be leaving that day, it ended up being cancelled. We were at the airport for 9 hours before they cancelled which meant that rebook in a flight on a different airline cost twice as much and was difficult and could only be done for the next day. Customer service was useless. The gate crews are third party contractors and can't do anything because of frontier's policies. I reported them to Dept of transportation and they keep sending the response that they have too many complaints to respond to and they wI'll get to it eventually."
Cons: "Terrible service from Denver. Missed flight due to Frontier check in desks being overwhelmed. Was there two hours early, told to go to outside curbside check in. Terrible delays when returning to Denver on the plane. Was held on the aircraft for 40 minutes before they could get us off. Bad experience. Won't be flying frontier again."
Cons: "The flight attendants spent the whole flight playing, loudly talking and eating. Made it difficult to rest."
Cons: "Although the plane assigned to our flight arrived at the gate timely, Spirit chose to re-route that plane to a different location. This resulted in a 4.5 hour delay for our scheduled flight. Consequently, I cancelled my ticket and overpaid for a more timely flight to Houston."
Cons: "I had a round trip with Spirit and on the first flight I could take carry on bag for free but on the second flight they sent messages about payment carry on bag $ 45. Also it was dirty on the board and the water they sell for 3$."
Cons: "We were delayed two times and the seats were very uncomfortable.. by butt still hurts"
Cons: "Didn’t like that we didn’t get a snack or drink like you do on other flights I had a headache and couldn’t take anything for it cause I didn’t get anything to drink"
Cons: "The bathrooms were disgusting. I understand that the flight crew can only do so much, but they didn't do anything after they were told more than once that the bathrooms were gross. They just gossiped with one another. Also, I am a teacher abroad and have been to many countries in many flights, but this is the first time I have ever been sick in a flight. My head is throbbing from the change of pressure and in all of my years of flying, I have never felt like this. it was a poor experience, and I will be grateful when I don't have to fly with Spirit airlines in the future."
Pros: "Man at check-in counter was very nice for baggage check More than anything I am very happy with pilots' performance. Landed airplane in a driving thunderstorm which did not seem routine."
Cons: "Weight limit for baggage (normal fee) is low: 40 lb instead of 50 lb."
Cons: "I missed the flight, just because they asked me to print the boarding pass. The printing device in airport didn't work and I ended up standing in a line for assistance. They asked me to go through the security check and they promised they sill inform the gate that I am coming. When I reached the gate,I got informed that the flight is on air 15 minutes before the departure time. No refund and no reschedule provided."
Cons: "they were rude and uncooperative. They have no type of customer service. If you ask them a question they are short and direct. If you try to work out to find a solution...they just are plain rude and do not make an effort whatsoever to accommodate their customers. They abide by their ridiculous rules and plainly will not work with you. Besides that they started to charge for separate baggage fees. So you'll but a ticket for "cheap" but then they will charge you double for baggage both ways. My boyfriend purchased a ticket and wanted to make changes...they wanted to charge him $100 to change flight info. RIDICULOUS. He ended buying another ticket....Spirit took $200 in fees extra from us."
Cons: "They cancelled the flight and were not helpful at getting another flight. I had to go with a different airline at the last minute."
