Check in process was terrible. Lady at counter didn’t know what she was doing

Check in process was terrible. Lady at counter didn’t know what she was doing

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

The crew was amazing; Von, Vera and Guadalupe were very friendly and attentive throughout the entire flight. They were friendly and welcoming to everyone. A solid and dedicated team for sure!

Terrible. I was bumped off of my original flight and spent the next six days fighting to get back on it. I lost hours of my vacation trying to get this situation corrected.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

International baggage recheck process in Philadelphia was a disaster. Waited 1 hour and 45 minutes to receive our bags. Waited 15 minutes to recheck bags, flight notification boards were blank so we asked an AA representative for our connecting gate and we were directed to the wrong terminal and gate. Our connection window was over 3 hours and we made our flight by 5 minutes. We pulled away from the gate and sat on the runway for 1 1/2 hours. 1 of our 4 bags didn’t make it to Phoenix. The mobile app for lost baggage didn’t work, the AA rep had to manually fix.

I miss my flight and they could not rebook me that day because the other flight was full, and for the next day I had to pay a whole new fee again which I think is unprofessional

The flight had a delay that made me being in a real rush to take the second flight. The delay was almost for 2 hours. They moved us from gate to gate in 4 times. Once I arrived to Philadelphia, I got to run thorough all the airport, as the train was already closed by that time. So I got sick with asthma for all the running I had to do. And I was the last one to board, when it was almost closed. So irresponsable with the people

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Overall, a good experience. The food, however, was subpar. The breakfast was a joke.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

Everything was great except British airways lost our luggage that was gate checked all the way through to Italy. No one knows currently where one is and the other one may be in route to Amsterdam to meet us but not sure. If you can Hale’s it would be awesome. The website is not helpful.

Seats were roomy. Lavatories were surprisingly big and clean. Plenty of entertainment available. We were fed and offered drinks, multiple times during the flight.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

The staff was excellent and I appreciated the zero tolerance for noise making electronics and the only bad part was It took forever for the luggage to get to the baggage claim. It took over 40 minutes. And Norfolk is a small airport so it was probably airport. Staff’s fault.

The flight was 3.5 hrs delayed. I was not notified prior to arriving to the airport via spirit app. or via boarding pass that I already had loaded on my phone. The agent that i saw at the counter didn’t mention anything about the delay either. I only saw the update after logging in to my email account.

The flight and boarding process was smooth. Wifi was unavailable and I prepaid for it. Have requested a refund

Offer snacks for free. You are charging for the flight for the carry on for the seat and for a snack??? Lord

Had a issue with catching flight due to airline, was unable to board flight

Spirit is a very uncomfortable travel experience. It’s cheap but you are squeezed into the seats like canned meat.

Not great. Seats uncomfortable. Crew a little rude. Amenities like wifi and drinks way too expensive.

We paid for upgrade seats (3A & 3B) the seats on front and the seats behind us got complimentary water & soda, but we got charged, had to pay for everything. Does not make any sense ?

Departure was right on time. The Orlando base crew from Atlanta to Puerto Rico was the BEST. The return flight crew was OK.

Spirit charges you to breathe in their presence. They have you pick and buy your seat in advance and then I got bumped from the seat I paid for because THEY overbooked the flight by a dozen people. they do not provide any entertainment, they do not provide even a small cup of water - you have to pay for everything. I will never fly Spirit again.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.

Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

The ticketing agents were rude but then we had a great gate agent very nice we had to ride a buss out to where the plane was parked but it was in some back corner of the airport when we got to the plane the captain who was great btw was cleaning the plane because the same rude ticketing agent told them they we not contracted to vacuum the plane. The ride to las Vegas was fine We had a connecting flight to Dallas. The flight was fine but when we arrived in Dallas everyone who flew on any frontier airlines the picked up bags from baggage claim D15 had to wait over a hour for their bags to start we arrived at 11:30pm ish to the gate we didn't leave the baggage clamed till 12:50 am very not happy and i used to fly frontier 4 times a week for work in Denver i will not be using them again

I was 2 hr arrive in the airport and 45 min in the line . After take to my turn . The agent tell me I’m later . I can not board . So my vacation was going to the floor . Just for their bad customer service agent in the airline

Frontier Airlines was AWFUL. I was an hour early for my flight and the lady refused to check me in. I had to purchase a whole new ticket with a different airline.

My flight was canceled I was promised a reginf still not received.

Late, terrible communication, horrible planning of passenger seating until the literal last minute. One of the worst flying experiences of my life. Y'all suck

Both legs of the flight were changed. The day of the flight and length of the trip.

First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.
