It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

I love no assigned seats and bags fly free. If Private Equity gets their way and forces Southwest to change they will be everyone else and I will stop being loyal to them. DON'T CHANGE YOUR BUSINESS MODEL!!!

The plane wasn’t full, so we got the best seats

Crew always seems to be unprofessional no matter what Southwest flight I fly

The 700 model seating is too tight both seat size & leg room

Being paid like a full service airline , I felt some features like no screen on seat, very poor entertainment content and no headphone provided. I like the checked bag benefit. Open seating concept is not nicely implemented as people were boarding out of order.

Southwest failed to leave on time forcing us to circle the airport due to weather. Please stick with the schedule and delays won't stack up.

Seats are tight. You pay extra to get to board early so you can sit with your companion. If not, you possibly will end up sitting in a middle seat if you are boarding group C.

Flights were full but SWA still managed to get everyone loaded and depart on time. No snack or beverage service on the first leg due to turbulance. Seats were clean but very little cushioning. Reasonable amount of leg room.

Great no problem boarding suitcase on time for pick up

Flight heavily delayed. No food available despite purchasing an upgrade. No in cabin service.

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.

Wifi did not work and they only served water, coffee, or tea.

The plane was very warm upon entering. This was a bigger problem as the weather was cold so people were dressed accordingly.

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

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

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

Great - This was the last flight before hurricane closures and did a quick turnaround to get the plane heading north. Much appreciated.

Coach seating is debilitating, neither my husband or I can walk the following day

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

Liked that we left on time for each flight. Snacks not the best, but we're okay.

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

Pleasant service from the crew. Arrived early. Efficient boarding and deplaning. Great job!

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

I am not an electronic savy. I don't know how to maneuver the APPS for services. Why can't I just buy food without the apps.

Flight home lot's of room shame I never noticed that they ripped my suitcase and didn't notice it to I got toy destination and had to buy new set

I was pleased and I had a very good experience. The staff was friendly and attentive.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

I missed my connecting flight despite requesting a wheelchair and had to wait at the airport for an additional four hours

The First class experience was really good!! Customer service was excellent.

Airlines changed our originally booked flights. Our luggage was completely damaged.

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

No complaints. Good WiFi, great crew and excellent speedy baggage claim

Flight was on time, no drinks served on the two short flights. Comfortable seats.

This time there was nothing to be better, really! Boarding on time, taking off on time and arriving earlier. The only complain is about way too long line at pre-check security point at DFW. But this is the airport’s problem, not American Airline.

3 hours late. Second consecutive time this month that a flight from DFW was delayed 3+ hours.

I was bumped to first class so I got some food. It was OK. Entertainment is whatever you bring with you since there are no seatback screens.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.

Stuck in Phoenix for two days, not even a hotel voucher offered.

Every day about it was very different all the boarding pass where all wrong l miss flight no refund all crazy

Flight got delayed for 3.5 hours, and for the first hour after the departure time there was no update from the gate folks...

Both flights were delayed. The sizing of bags is crazy. I know it is advertised as a no frills cheaper option but it does feel like you are being extorted for money the whole way-- $20 dollars to talk to a gate agent? Charging for soda a pretzels? I don't think I will be flying Frontier again if I can help it. That said, all the staff were wonderful.

Staff members pretty horrible when boarding. No care for customers

Frontier is definitely a good option for people traveling light or on a budget - just remember to bring your own entertainment and your own headphones if you need them.

The plane was very clean, the flight attendants were chipper and accommodating. It was roomy

I didn’t have enough time to catch my connecting flight and had to use a different Airline. I will be requesting a refund.
