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

Above and beyond effort from this crew in a tough situation. So helpful and understanding. Thank you!

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.

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.

Late departure by 1:45min. No explanation why. During boarding inconsistent policing of their baggage rules. Before takeoff and lamdimg strange obsession with window shade and armrest positions. Don't know why they care. 15 min tarmac delay on arrival, they blamed airport congestion but we were the o lh flight waiting, it was clear it was due to poor staff planning (only one ground crew to receive airplanes and multiple arrivals) Got there but was rrally lame the whole trip.

The seat belt was lengthy enough that I did not need an extender. Courteous and helpful flight attendants.

We sat on the tarmac for an hour waiting for a gate to deplane.
