Pros: "Comfortable seats and smooth red-eye transcontinental flight."
Cons: "If there weren't a 15-minute delay due to maintenance."
Pros: "The two member of the crew were very welcoming and kept a very good sense of professionalism along with adjustments to every passenger. I can consider myself a frequent flyer and it’s relieving to have a crew like that."
Cons: "I would appreciate a quicker and just a little bit more organized check in and maybe some different snacks that will make an airline stand out."
Cons: "Delay on takeoff and a delay on arrival. Flight Attendants never offered headphones for purchase to watch in filght movie/TV."
Pros: "Super easy boarding and friendly staff."

Cons: "my seat wouldn’t stay up, it was a little broken"
Pros: "Alaska is my favorite airline."

Pros: "More room in economy than other airlines. Thanks!"
Cons: "Still miss the live tv programs from Virgin America days."
Pros: "The only enjoyable thing about my flight was the couple sitting next to me."
Cons: "We weren’t served drinks until nearly 2 hours in. They kept making announcements saying “it’s really turbulent and not safe” but I’ve flown a lot and we barely had any turbulence the entire flight and at no point was it unsafe. When it was calm they were hanging out and taking in the back."
Pros: "Half of the flight was empty. I asked of I could move to the row behind. I was told that was premium seating and I didn’t pay for that. I didn’t appreciate being addressed like that. And did ot really matter when nonoe is sitting there or plenty of other seats."
Cons: "She could have just let me sit there. I should have been told that the seat didn’t recline when the ticket was pirchase."
Pros: "The seats were very comfortable even though legroom was limited in the basic cabin."
Cons: "Delta delayed the flight from LAX to SLC, which subsequently made me miss the connecting flight from SLC to ORD. Completely unacceptable"
Pros: "Overall, flight was great."

Pros: "I did not like nothing"
Cons: "Custom took for ever they only had 2 agents working and I Missed my fight to nyc"
Cons: "Sat on the runway for over an hour to get the gate. Unacceptable."
Cons: "Double booking and payment of flight. Dropped flight bookings. Not a good trip"
Pros: "The attendant was most helpful. Because the flight was not full, she allowed us to sit in the exit row, window and aisle, with no one between. I'm a tall person, so the extra leg room was deeply appreciated. I give her and the airline high marks."
Pros: "The crew members were very friendly"
Cons: "Coach seats still a little too small. Always bump the person next to me"
Cons: "Due to the earthquakes, the film festival I was going to was cancelled. Ten days prior to the flight I called AeroMexico to cancel and they said there would be a cancellation penalty, which was fine. When I tried to redeem my credit, they said there was also an additional "No-show fee" even though I called to cancel 10 days prior, which left a total of $70 credit after all their penalties. I called and emailed to complain but they did nothing but pass me to someone else who was equally unhelpful. I will never fly AeroMexico for any reason in the future."
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"
Cons: "Paid for First Class so I could sleep on this red-eye. Wasted my money. Seat was uncomfortable, legroom in my bulkhead seat was horrible. I can sleep anywhere...make that ALMOST anywhere, now."
Pros: "Clean plane, fast boarding process."
Cons: "No power to charge a device. This really is unacceptable in today’s world."
Cons: "Caught an earlier flight and the entire team made the process seamless."

Pros: "A 2 hr delay after boarding with precious little communication from the crew."
Cons: "Flight was delayed an hour. Poor communication with passengers during the process."
Pros: "On time arrival"
Cons: "No movie screens, no video screens, no charging options, no blankets, no pillows, no fun."
Pros: "the ground crew gave me an express pass to navigate pass the Summer Holiday TSA queues. Was worried I was going to miss flight. So that’s was super good of ANA ground staff at LAX!"
Pros: "Crew was nice."
Cons: "How much do United Engineers get paid? They can’t figure out how to make the last row recline? And why was this particular flight not able to let me select a seat?"
Pros: "Nothing, the seats were really horrendous, the head rest was in such an awkward position that it was better to attempt to hunch over and try to sleep on the tray. The lack of leg room as well made it equally uncomfortable. Seriously, the most uncomfortable flight I have ever been on."
Cons: "See above."
Pros: "Did not have any food so an N/A option for this category is needed."
Cons: "The exit, economy plus seat I chose was described as limited recline when it fact the chairs do not recline at all. I was so disappointed. Had I known this, I would have chosen a different seat. My neck was hurting by the end of the flight."
Cons: "Seats with little cushion that make you sit virtually upright for over 5 hours."
Cons: "Would not allow upgrade even thought seats available because my economy ticket was not appropriate for upgrade. Seems that if all those who could upgrade hf upgraded had done so, why not allow the upgrade. Would have been more money for airlines and I would have enjoyed the trip more."
Pros: "Most of the crew were friendly but some board and inattentive"
Cons: "Paying for food and movies"
Pros: "Nothing."
Cons: "My seat was changed without my knowledge or consent and no one was able to tell me why or fix it. I spoke with a united customer service supervisor and have yet to hear from anyome about it."
Pros: "The crew was wonderful; I purchased a business class seat, which was comfortable (although I could not tell the difference between business class and coach seats)."
Cons: "The food was horrible - nothing fit for a person who is diabetic or vegan or non-dairy. And the price was outrageously high for what one received."
Pros: "The seat next to me was empty which made the whole long flight more bearable."
Cons: "Typical United service, without any bells or whistles."
Cons: "Spirit airlines is a joke. The seats are very uncomfortable, and they do not recline. Torturous."
Pros: "That the flight was over"
Cons: "Had to pay for flight, tiny sardine seat, water and people on flight were in a huge hurry to exit plane at gate, hardly waiting for row by row polite deplaning. At least I had an assigned seat! Baggage took a long time to arrive. The crowd on flight were very loud - awkward personal conversations. Crew were good."
Pros: "I remember I used to fly with spirit and they were the worst airline. I can tell now they have changed a lot and they have improved in all ways. No delays"
Cons: "They should at least have water for the passengers. But in overall it was a pretty comfy flight."
Pros: "Bording was fine"
Cons: "Horrible costomer service, nobody knew there job. Never flying spirit again"
Pros: "Had a row to my self. Comfortable."
Cons: "The cost of checking bags and having to pay for a seat. I thought when you purchased an airline ticket it included a seat. Imagine my surprise when I had to pay for a seat."
Pros: "Crew was friendly."
Cons: "Late 4.5hrs, several false "we're boarding now". No communication of what the issue was. No in-flight service, even a soda wasn't free. Never again."
Cons: "The baggage "stuff" is so confusing. Really, charging for carry ons, come on that is crazy. It is presented in poor fashion."
Pros: "Seats are the most uncomfortable I've ever experienced. Maybe acceptable for short flight, but more than 2 hours never again."
Pros: "Horrible airlines. Worst experience I have ever had flying. Terrible Costumer Service. Hidden costs everywhere. I will aggressively spread the word for people to not use this airline."
Pros: "Attendants were very polite and funny!"
Cons: "Delay on runway, in-flight transit was faster overall. Same or earlier arrival. No complaint."
