Pros: "Pleasant. On time. Friendly. Decent value for money."
Pros: "The TV was nice"
Cons: "Some of the most uncomfortable seats both to and from Denver that I have ever sat in. Felt like sitting on a stone park bench. My back still aches 2 days later. It was a redeye, so I didn't much interact with the crew, but they seemed efficient and professional. They did not wake up during drink service, which was appreciated. Those planes suck!"

I requested earplugs, and wore them under my 34 dB noise isolating earmuffs (which were made for use at a gun range). The screaming was still loud enough to give me the worst headache that I've had in 4 years. Once this baby stopped, the baby in the row behind me began to scream and the one across the isle from him/her joined in. I would happily rebook with JetBlue if there was an option to not be seated within 5 rows of a toddler."
Pros: "Great trip, but the mini tv wasn't working which was a bummer."
Pros: "Boarding from back of plane"
Cons: "Didn't get snack I asked for and what I got (popcorn chips) I didn't like. Also chair wouldn't recline"
Cons: "Online check in refused to let me pick a seat even though the plane was not full. It then did not generate, or allow me to print at the airport, a boarding pass. When my connection arrived at 7pm I stood in line at the gate while the airline employee working completely ignored us for a solid 15 minutes waiting to get my boarding pass. the flight then said it was delayed with a departure time of 9:05 and we did not even start boarding until after 9pm."
Cons: "When the flight is cancelled you need to find a solution for those passengers who travelled that day by bus or car just to catch the flight!!! At least a hostel to sleep over night or give them back the money or let them travel with another company...not to wait 12 hours on the airport!!! Thats not professional at all!"

Cons: "Nothing all excellent"
Cons: "It was great! Nice job Delta !"
Pros: "Great crew."

Pros: "Christina brown was amazing at gate"
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Cons: "Great flight"
Cons: "crj900 from BUF-MSP is a wreck. worn out, uncomfortable seats, cold air coming from floor toes were numb for about 20m after flight. Flight delayed, missed connecting flight, lost comfort+ upgrade I paid for. No excuse for pitch in main cabin on 737-900 ER."
Pros: "Nothing remarkable"
Cons: "Delta was ordinary"
Pros: "The crew and entertainment options are great. Relatively comfortable seats by today's standards."

Cons: "No meal option and my video screen volume did not work"

Cons: "Boarding at JFK.Always messy"
Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"
Pros: "Delta cramps people into these planes and forces you to put your bags under a seat because they stuff at the overhead spaces. They nickel and dime you for every single thing. There was even one person I saw who had to pay for his headphones to listen to the onboard entertainment. I think Delta should quit being so cheap with the profits they make and give it back to your flying customers. It borders on gouging."

Pros: "Entertainment choices were excellent, many new movies available, so I was able to see movies is been meaning to watch. There were drinks available."
Cons: "The air vents barely trickle out any air anymore. No relief to be had. Airline crews say hi and goodbye but that doesn't make them friendly."
Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."
Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."
Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"
Pros: "The Delta service desk was great! We wanted to get an earlier flight home and the Delta Rep got us on standby quickly and with a smile."
Cons: "Some chaos getting on the flight. The area they have set up for the different sections to wait before getting called weren't marked very well so everyone was bunched up and confused. Once they started calling the sections it was fine. Not sure why they even had the marked areas."
Pros: "My upgrade and breakfast were fabulous!"
Pros: "Staff very courteous and professional"
Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."
Pros: "Everything was perfect !! Staff friendly"
Pros: "Great in every way"
Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"
Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."
Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"
Pros: "really helpful and friendly service and nice seats."

Pros: "to their Diamond Medallion customers"
Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
Pros: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Return trip was 30 min ahead of schedule"

Pros: "Very professional and caring."
Pros: "plane had individual movies for free with each seat!"

Cons: "just about everyting"
Pros: "Entertainment on seats"
Cons: "I sat in seat 12A- the window was so hot it was burning my arm and I was extremely hot. Not sure if it’s from the engine heat or sun but it’s probably a mechanical issue that the 737 should address. Horribly uncomfortable trip."

Cons: "Flight got delayed. We paid for assigned seating for our almost 85 yo mom. And the change in flight no one asked for to get seated in the front of plane. Instead she was seated all the way in the back. It was physically exhausting for her."
Pros: "The notifications regarding my connection and baggage claim."
Pros: "Crew was great"
Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."
Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."
Pros: "No major screw-ups this time!"
Cons: "It's AA, let's not try too hard here."

Cons: "Gate lady was funny about being pissed about the delay."

Pros: "They got us there quickly."
Pros: "Ahead of schedule"
Pros: "Plane was surprisingly spacious in coach and very clean."
Cons: "They seemed to have entire plane boarding in group 6. Hardly anyone boarded in groups 1-5, and when they called 6 the entire gate area lined up."

Cons: "No tvs!!"
Cons: "the new seats are awful"
Pros: "It’s been a while since I’ve flown American, but the aircraft was updated with a solid multimedia system, great moving map, and a standard power plug and USB port at every seat. That’s more than I expected, and was quite happy. Service was solid—no complaints."

Cons: "5 hr delay"
Cons: "We sat on the runway for 3.5 hours while the crew cleaned up a fuel spill and we waited for a different co-pilot."
Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

Cons: "Delayed boarding, no room in overhead bins even after being charged extra for carryon and had to stuff it at my feet, even at row 15, after being charged more for that too."
Cons: "It sucked in many ways. But that wasn't united's fault. The weather was threatening lightning in Denver and of course because of that the world stops turning."
Cons: "There are hard to reach outlets and no ports to charge a device without a box. Also, no monitors."
Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag. What is baffling is that when I arrived at Denver people were getting complementary check in baggage. I’m so dissatisfied with the booking and the amount it has now cost me ruining any savings I’d had for sanfrancisco"
Cons: "The boarding process was chaotic and the plane attempted to land once, got about 100 feet from the ground and had to pull up. So we basically landed twice."
