Airline reviews
Pros: "The person next to me was drunk. The crew was rude."
Pros: "The person next to me was drunk. The crew was rude."
Cons: "Packed flight but the crew and ground staff opened to back door to board more easily. Thanks!"
Pros: "Crew was very relaxed and friendly."
Cons: "Boarding was actually very good. It’s just the worst part about any flying experience. But they have a great system."
Pros: "Crew was friendly. I loved that I could charge my phone as well as text while in the air (for free)"
Cons: "Delayed by 3 hours with nothing more than a sorry"
Cons: "We will move from our original reserved seats to the last row. Gogo system not operative."
Pros: "Service vas very good. The flight itself was unremarkable. Take-off and landing was smooth and on time."
Cons: "The airline knew I was connecting, and they left early. No compensation, last flight of the night."
Pros: "Boarding was a little slow but the overhead bins were a total win! Love the bigger compartment! The seats were comfy and the flight crew were great! Plenty of complimentary drink choices and delicious snacks that could be purchased. Free in flight wifi was awesome and loved being able to charge my tablet at my seat."
Cons: "Needs wider seats, more help with boarding so it could go smoother and faster. More than one passenger struggled to raise the arm rest."
Pros: "No one in the seat next to me and we got there 20 mins early"
Cons: "Deboarding is always a hassle, nothing really bad"
Pros: "Very professional and helpful especially Ms Sahar in Ontario airport."
The counter service folks didn’t show up until two hours prior to the flight. The check in machines didn’t work, ALL CLOSED. Slow service, few directions. The plane was clean, but the restrooms need work from a space standpoint. I am 5’8” and I had to bend down. Very cramped and I am a thin person. Too bad it’s “profit over people” corporate mentality…
Pros: "We've always enjoyed flying Delta and this trip had been just as nice as the previous ones we have taken through this airline."
Cons: "Our stewardess/stewards seem to be incredibly cranky on this trip and very unapproachable. They must have been having an "off" day I guess."
Cons: "Everything was great! Would love to be a loyal Delta passenger. I wish the prices were more competitive. Willing to pay more for the quality of experience but Delta always seems sky high!"
Cons: "I’m a pretty big guy so this won’t apply for many other people . But the seats didn’t have much space . It was a very uncomfortable experience. I have taken many other flights and this one was one of the worst."
Pros: "The cabin crew was helpful and professional"
Cons: "Having better time performance . The first leg of my trip was so delayed that I almost missed my connection."
Pros: "Crew was nice"
Cons: "All tables in economy class are broken for both flights - tables sit on you lap. Plane is very old with very small tv screens"
Cons: "Plane had to divert from Salt-Lake City due to a storm. My son 17 years old traveling alone once in Salt-Lake City should have been given priority for an overnight stay instead of sleeping on an airport bench! Dinner + Breakfast vouchers would also have been nice compared to the 15$ food voucher..."
Pros: "The check in counter personnel was VERY UNHELPFUL. I was running late to previous Delta flight baggage delay. The counter person would not let me check in even though I still had good 45 mins before take off. AND THE PLANE WAS DELAYED BY 40 MINUTES ANYWAY! I never made the flight, had to take train."
Cons: "The entire Delta customer service was a nightmare. Delayed flights, literally lying supervisor who escalated a dispute, absurdly poor service. ASSISTING A PASSENGER WITH A TRANSFER TO ANOTHER DELTA FLIGHT AFTER THE FIRST ONE WAS DELAYED IS "NOT A GUARANTEED SERVICE". Seriously, it is basic courtesy!"
Pros: "they let me drink the whole can of soda..."
Cons: "turn lights on during service. be friendlier. allow to purchase seats anywhere BESIDES the middle seat. seriously?"
Pros: "Crew was amazing."
Cons: "Delayed departure due to late crew arrival. Not a huge deal."
I appreciate that the flight boarded and departed on time and landed slightly early. However, the plane was completely full (I suspect overbooked) and took a long time to board, during which time the CO2 level in the cabin climbed over 2,200 ppm, which is NOT SAFE given that COVID-19 is still being transmitted at a substantial rate across most of the country and airlines no longer require passengers to mask. Also, the midflight credit card sales pitch was tacky. It's like our airlines are being run by Ferengi.
Pros: "Crew was very accommodating but all three of us passengers were very close together, Thank goodness we were all considerate of the other."
Cons: ", Thank goodness we were all considerate of the other.Just need a little more elbow room for a comfortable flight."
Cons: "INTERNET is difficult to figure out in these AA flights"
Pros: "We finally got here."
Cons: "Communication about the delay , which gate we were leaving from, having an entertainment system that worked (they said I could use my device with the app downloaded, but it did not work, I kept getting an error)."
Pros: "Not much crew stayed in back almost the whole 6 1/2 hr flight and seemed not to friendly"
Cons: "It would have been better if they had departed when they said they were going to after a delay. Flight was delayed first 1 hr then two more hours. The airline finally posted that it would depart a 4 PM and we didn't even start boarding until 5PM. Then they tried to rush us on so that everyone was standing on the HOT jetway for 10 min waiting to get on the plane. Plane didn't take off til 5:35 PM. Over all on this trip I had three flights that were delayed. I'll think twice before taking American Air again."
Cons: "Checking bags in PHF very poor. Disorganized and poorly managed. Staff needs more training and explicit direction. Kiosks should ALL be in working condition!"
Pros: "Nothing"
Cons: "After this I need direct flight from DXB to LAX"
Cons: "It ridiculous how small the seats and aisles are. It not fun flying any more"
Pros: "Only the food on this trip was good. Everything else had issues."
Cons: "Poorly organized boarding at Miami. Agent did NOT speak clearly. Uncomfortable long walk outside uphill ramps and steps to board on the a tarmac. Purser’s PA system only worked occasionally. Most communications relayed from rear. My first class seat in row 3 was broken partially reclined."
Cons: "on a 5+ hour flight, that was diverted back to the originating airport due to a passenger who had extreme DTs from excessive drinking the night before, and made the flight return, American offered NO compensation AND the aircraft was so old, there were NO back seat monitors NOR any means to charge our electrical devices!!!"
Pros: "The entertainment is amazing. Did not expect it. Just download the UA app and it is connected to your device"
Cons: "Not their fault but we were detailed total of 3 hrs from Ontario to SFO and SFO to HNL due to aie traffiv in SFO. They handled it well"
Pros: "Crew & flight attendants very courteous and apologetic; complisnacks while waiting for delayed flight"
Cons: "Flight delay!!"
Pros: "We were on time and the flights were excellent. Liked the way the pilot and the crew interacted"
Cons: "Arrival time was delayed 2 hours and my itinerary fell apart. United could not assist me. I bought a ticket from Alaska Airlines from a different airport.to JFK."
Pros: "Flight attendants tried but could not change situation"
Cons: "I losr one of two days- moving furniture Have to stay up another night to getready"
Pros: "Easy, convenient and everyone is nice and accommodating. We always get to SFO under an hour"
Pros: "The fact that I got fully refunded, even though I still lost out on $500+."
Cons: "My flight was supposed to leave at 12, and all that Kept happening was me receiving text messages about delays pushing my departure time back to 5:35pm. I missed a big birthday event I was throwing for my class that I teach, lost out on money spent for the event and missed out on all the memories made that night. I never got to leave, ended up cancelling my flight. What a waste of time. Seems to always happen when I fly through United."
Pros: "i was rebooked and am still on my way"
Cons: "i was delayed in ONT, making my flight an almost 24 hour trip from vONT to my destination. not fun had to reschedule car rental. luckily, they did not charge extra"
Pros: "Nothing"
Cons: "Air Canada flight from Ontario to SFO was operated by United. Our flight was delayed by 2 hours and we ended up missing our connection. The customer service on the phone from both Air Canada and United would not take responsibility and continued to advise to call the other company to reschedule the flight. Not only did we miss our connection but our checked bag was rerouted onto another flight with no formal notification."
Pros: "I liked nothing about my flights."
Cons: "I hated that my first flight was delayed a whole day and I had to fly out of a different airport to get to eugene. To add coming home I tried to upgrade my flight to Ontario to an earlier time and they refused to do so and said it would cost $75. I felt the least the airline could do was let me fly home an hour earlier since they delayed my flight a whole day but that didn't happen."
Pros: "The crew was reassuring when we were running to board and helped my husband, who had trouble walking."
Cons: "Seats are very uncomfortable. I was charged for my personal bag"
Pros: "It was good"
Cons: "All those extra fees even for a drink!!! First time on frontier not sure if I would use it again"

Cons: "Make the seats more comfortable with more leg room"
Cons: "Offering WiFi would make the cramped and uncomfortable seats a little less unbearable."
Pros: "Crew was awesome ! The flight crew I would fly with anywhere, anytime. No mucking around ,get in , buckle up, we’re outta here . I love that ."
Cons: "I’m 6’2” , any vehicle other than my R1 is just not super comfortable. Even my truck and i love my truck . But anything over 2 hours starts wearing on my long legs . Thats my issue . Nothing any airline can do for that . I prob need to opt for 1st class next time n see ."
Pros: "I made it safely to and from my destination."
Cons: "The seats are very uncomfortable, lack padding and back support."
Pros: "The staff was nice"
Cons: "The check-in process. The upcharges on everything. Barebones flight."
