The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

The WiFi has been awful on my last few Delta Air Lines flights.

The woman in seat 1A was allowed to bring a dachshund dog onboard. It smelled terrible and the odor wafted throughout the first class cabin. This was clearly not a service dog and should be prohibited. I paid for the highest class of service, and this was a disservice. Why is Delta allowing this? I may reconsider my future flight choices.

Only one side of the heafphone jack work. Crew was friendly and helpful.

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

Flights were terribly delayed. I was at At,anta Airport for over 4 hours waiting for my connection.

Older plane and it came with Fleas and flea bites!

All good on Delta's part. Passengers could be a little more courteous to each other.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

I was forced to check my carry-on backpack despite there being space - but it came out on the baggage carousel so fast it didn't even delay my pickup. Otherwise a good flight. Boarding began early (which was disadvantageous for me) but fine.

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

The plane’s radio wasn’t working. This delayed the plane for an hour and a half. Then we all broaded and taxied down the runway only to get called back because the radio was still not working. Had to get off the plane and then find another plane making the trip 4 hours delayed. Maybe a different plane should have been chosen sooner?!?!?!

Late out of the gate, late to takeoff. No screens on plane. Uncomfortable window seat.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Your seats in the last 5 rows are terrible. My knees were jammed into the seat in front of me and the lady sitting there decided to recline it. Jammed my knees bad. I don’t know if I’ll fly United again.

Pot and crew did a tremendous job landing in Savannah in the middle of the tropical storm. !!

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

The plane was very warm and the crew turned on the lights for the entire snack service.

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

Checked in the minute I was allowed and still wound up in group 8 for boarding.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

The flight was delayed which was disappointing. There was no pre takeoff refreshment in first, as we had to wait around an hour in our seats before take off that was disappointing too. The inflight entertainment/wifi did not work, and the crew were slow to offer drinks in flight

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

Flight was delayed , waited in the tarmac for 3 hours and then came back and was cancelled

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

I thought since I upgraded my seat I would get some perks. Free water, free snacks. Free carry on luggage.

Terrible all around. Not much else to say, other than an awful experience from start to finish.

Boarding procedure is horribly slow. You charge me to check a bag and would not let me carry it on. Charged me to simply select a seat. Charged me for water. Charged me for every little thing on top of paying for an expensive ticket. Your seats are terrible. So uncomfortable, they don’t recline. No WiFi, no way to charge my phone. No entertainment. I mean you Offer noting and you charge for everything. Why would anyone want to fly with you again?

Customer service. There is no way to call them and online chat doesn't deal with your specific concerns. I don't plan to fly spirit again.

Flight delayed. Seat assignment doesn’t get assign until last minute. Seats don’t recline and very stiff

Better overall experience from my first flight with Spirit several years ago. Efficient boarding (albeit I arrived after all rows were called) and flight actually left earlier than planned. I am still baffled by being charged for everything, even a non-alcoholic beverage. And there is definitely less seat room which makes a flight that’s more than 2 hours really uncomfortable.

This was the best spirit airlines fight I have ever had. I take spirit up to 3 or more times a year and I am ready to be the Jared of spirit. 🤪 Best flight ever. Everyone was great. I hope my return flight is the same. When you're traveling with a 9 month old you need a different type of care and accommodation. I didn't ask the staff for anything but I didn't have any added stress.

Would have been better if I would’ve made it on my flight but it was delayed twice and then canceled and now I’m stuck till Monday which was and extra 5 days I did not count on .

Both flights were delayed. Flight from LGA to DTW caused serious anxiety as 3 people were removed from the aircraft before take off for disorderly conduct. Extremely uncomfortable to be in that situation. Staff handled themselves okay- definitely could’ve been more professional and deescalated the situation first. No apology for the delays at all. No water, no snack, no nothing. Not a good flight experience.

Cancelled the return flight moments before boarding, horrible customer service in assisting with any rebooking. Never again will I fly Spirit.
