Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

Airline is not very senior friendly. Flights are late, forcing us to run to the connecting flight. Food is awful. Wish they would go back to pretzels and peanuts. During flight, pressurization isn’t quite right and all of our ears get plugged. Everything is nickel and dime, charging for boarding, seat selection and legroom. While a screen at the desk in the gate area says check your roll on bag now for free due to space limitation, the employee at the desk will not check the bag without a $100 fee. Insane.

there were two flight attendants that were up front...that were the best! They get KUDOs for making my trip only fantastic. Tell them Jeff said that!

Seats were very comfortable. They tilted back. Drinks and snacks were free and served 3 times. Attendants were awesome.

Truly terrible. Will never willingly fly southwest again. Seats are worse than before they switched to assigned seating. One flight attendant was the opposite of helpful (rude, unhelpful, dismissive, and as my stranger seatmate said unprompted: a total prick). This caused me, 15 minutes into the flight, to book an alternate return flight home on a competing airline (first class 1.2k purchase instead of my existing planned flight) just so I would not have to ever be on that aircraft, with that terrible service person, with those horrific seats ever again.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

Great flight. I didn't get a drink because I was asleep whole on the flight.

Terrible all around. Left prior review detailing massive delay/cancellation to then rebook travel. Topping on the cake was lost luggage even after travel to ultimate destination was secured on a new plane(s).

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

They didn’t have any headphones for the entertainment screen and their USB port didn’t accommodate a USB-C for more modern phones. The food was just ok. The staff was friendly but the seats were very uncomfortable for a full flight.

I had to run from the end of terminal one to the end of terminal two to make the connecting flight....probably a kilometer. No electric carts were available. I'm 76 and literally had to run to make the connection at the last minute. The connecting time was absolutely unrealistic. When Last Call was announced, I tried to get other Copa gate staff to call Gate 221 to let them know I was on my way, but they said no. I came within 1 minute of missing the flight.

Boarding was a mess, they call all priority members without distinction so gold, platinum, silver were all mixed together in a long line which defeats the purpose

Avoid at all costs. My wife had to stay back on a connecting flight as her parents flight was delayed. 10 days later on the way back they cancelled all our flights. We had to rebook all four of us on the next days flight.

Seats were awful. Media should have been included for such a long flight.

Horrible. No TV or any type of entertainment on board. Passwnger listening to/watching stuff on their own phone with no headphones making it noise and uncomfortable for everyone else, little/tiny food portions, old seats, useless wifi (cant access anything). Horrible exlerience especially it was a lomg distance flight with kids.

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

It was so much better than expected, Ohare is not such a pleasant experience but American Airlines with the new, clean aeroplane and free Wi-Fi was outstanding and the crew so pleasant and helpful.

AA was a very good experience. The employees are wonderful

Typical AA - late by 90+ mn. Gate changed twice... Changed the departure time 6 times No explanation, no communication on reasons for delay I travel with AA twice a year... and it is consistently very poor.. I will continue to use AA only when i have to.

The flight attendants as well as the gate agent were out to lunch. Nothing extraordinary about their service. American just keeps getting worse every year.

The chicken wrap was tiny ($13 for what looked like a 1/3 of a normal wrap?) and disgusting.

I like that the flight attendant was very attentive and helpful. The meal menu could have more of an variety of food choices.

Broke my luggage and I can't get a resolution yet.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

The professionals have excellent customer service, the seats don´t have enough space.

You should have had Wifi to make it much enjoyable.

Easy experience even with the outbound flight being delayed. The seating and space was comfortable and the crew seemed very nice and helpful.

Flight was smooth, amenities (entertainment options and power outlets) were good, sears decent)

Flight team was very courteous only complaint wS the boarding process and mandatory bag check

My experience with Jet Blue was wonderful. My experience with Kayak sucked and will never use again.

Disaster This is why I stick to delta You get what you pay for

Still hasn’t left. Why are you asking how it was?

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

Absolutely horrible. Flight was delayed 4 hours and they had no clue what was going on.

Delayed our flight to accommodate another flight but didn’t make the decision to do so until we were supposed to board despite having all the same information hours prior. Arrived so delayed that we didn’t get a gate and had to deplane on the tarmac and get bussed to terminal in the rain after 1am. Arrived to the terminal and due to construction could not get a ride share - had to either take the air train to Howard beach or stand in line with 200 other people waiting for a taxi.

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 !!!!!!!

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.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.

Good- no snacks on a 4+ hour flight is painful but more painful was the lack of WiFi.

Horrible. I would never fly Frontier again. The booking process is tricky at best, but fraudulent in my opinion. Frontier customer service did nothing to rectify my purchase -- I ended up paying more than double what I could have gotten from other airlines and nearly triple what I thought I was buying from Frontier. Their booking practices are unfair to the consumer.

Inbound plane was on time and flight departed on time with no issues while boarding.

My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.

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