We had a 5 hour delay on the tarmac in Baltimore

Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

WiFi was not working and didn’t have a beverage service

Snacks are always pretzels. Why can't you also offer peanuts ?

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Terrible experience! delay 2 time and say i dont have ticket

Both my flight where delayed Had 25min to make it to my transfer flight

Would've been great if Lufthansa union cockpit pilots didn't strike for 2 days and caused a chaos to my returning plans to USA, and then after rebooking a flight 2 days later tge plane departed 35 min later. So I did not have a good experience.

Everything was on time and service on the flight was great!

The boarding in Buenos Aires (at the on ramp) was not great. They had to check every carry on. Not a United problem but was a Buenos Aires problem.

Staff and aircraft were good. However, weather in Houston lee to a ground stop. We were looking at circling behind three other planes until the stop was lifted. Pilot said we didn’t have enough fuel for that. So we flew on to New Orleans as the closest port with immigration and customs staff. Landed there and sat in the plane for two hours plus while staff was sorted. Turned away by ICE. Waited for pilots to be switched out, but after they were approved by ICE. Then had to wait to get a runway because so many planes were ahead of us. Finally took off and flew back to Houston. We all missed our connecting flights because it took too long. Hotel voucher from United was only a link to booking site. Total BS. Finally got a flight out the next day after a night without sleep because all the Houston hotels were booked by rodeo and spring break crowds.

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

Delay after delay with little communication then AA lost my luggage and at airport would not assist just said scan this QR code to track your luggage and submit a claim. However QR code provided did not work so have to go back to airport

After changing the departure gate 5 times making us mo e from one side of the airport to the other and then back the flight was delayed nearly 2 hours. The male flight attendant had a bad attitude with the guest being condescending, disrespectful with people who were already on edge.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

It would have been nice if American tried to care.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.

I booked 1st class, my flights were changed and I was sitting in the middle at the back of the plane. A far cry from the 1st class I purchased for my flights. I am grateful I arrived on time.

Movie selections were very limited. Meals were not f So good.

Older airplane with worn out seats. No entertainment system at all. Connecting to Wi-Fi was problematic and hit and miss.

AA is flying sub par aging 787's to Tokyo. I fly other 787's long haul and these are at the bottom. Seats don't work well, tray tables don't work well and were dirty. The flight was great, the plane was not.

There was no beverage service and the only time I saw a crew member walk through the cabin is when we were preparing to land.

Delay due to personnel issues on Spirit’s end. Original departure time 9:30pm. Took off at 2:15am. Lost an entire night’s sleep bc Spirit couldn’t get a crew together. Very poor.

Flight was cancelled without explanation or option for same day or next day flight

Had to pay for my bag a mini weekender bag 100 dollar fee

They charged late fees for selecting seats (no $0 options). They also changed my gate within the last half hour and are refusing to reimburse my costs to drive across the country with two small children in a rental car.

The flight from Boston to San Juan was boring since you guys don’t offer wings if during the flight. The returning flight was better offering WiFi to passengers. The food was horrible not enough on stock.serve paying customers better.

Forgot my anxiety pills, crew didn’t knew what to do then few minutes after they gave me a bottle of water and told me to walk thru the hall. They should be trained for this kinds of situations cause it really would help someone. Tips: bottle of water (airports should allow passengers at least having them thru) for this kinds of situations. Alcohol wipes just in case they don’t have. Tap water on skin (preferably little cold or a normal temperature) this will help.

the fligh was delay form 9am to 10, delayed again from 10 to 11, than delay and gate change to 12 and delay another gate change to 3;25 pm

Flight was cancelled with very little notice. Had to scramble to find transportation to my Mexico vacation.

Our outgoing flight was cancelled two hours before boarding and Spirit was not able to get us onto another flight. Their customer service was slow and unhelpful.

Terrible. I never made my trip to Puerto Rico and my layover flight from IAH to MCO was delayed over 3 hours and made me miss my connecting flight. I spend 2 days in an airport just to have to go back to Houston. This was a trip for my birthday and I lost money on this trip. I understand the situation with Venezuela affected flights but it’s always something with Spirit.

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

Frontier line changes my flight schedule with out my authorization. They never ask me and with out my concern they cut off 4 hours of my vacation they force my to leave 4 hours early from Puerto Rico.
