They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Both ground crew and flight crew were rude, and did not provide any level of service. They made it very difficult as we were traveling with a passenger the required assistance.

It was OK. The flight is pretty long for the airlines to only offer a simple sandwich on business class. The entertainment is similar to that on other Skyteam members. Ultimately the airline lost my bag and didn’t deliver it to me until the next day after a lengthy lost baggage report.

Good, the flight from Miami to Mexico City was better than Mexico City to Miami

It was good in general. The Crew during the flight were very nice at all times.

Annoying that we had to go to departures and get boarding passes. Should allow us to be booked all the way through, this is the only airline i have this problem with in MEX. Late boarding and take off

the guy in front of me put his seat back immediately...and then left it back including thru landing and taxiing to the runway. attendants did not check/ask him to put it up for landing.

This is not a low cost airline. Stop acting like o e.

Boarding - It is unclear where the line for the group are given the signs. A solution would be a diagonal arrow pointing to the lane in which the lane for boarding of a given zone should form. As it is now, you are guessing which side of the pole the "zone 3" sign is telling you to form the line. Inflight Entertainment - The Spanish subtitles function didn't work for movie watching (in fact, all subtitles didn't work), so was difficult to follow along and I watched the movie in silence without words.

An hour-long wait to check in, 90 minutes for luggage to come out, lost luggage, chaotic operations

No everybody brings the proper equipment to enjoy the plane entertainment. Then I was not able to enjoy it.

The money you save flying volaris is not worth it

In Mexico charges too much for my luggage and I ask for help and nothing one lady she just disappeared 😡😡😡😡😡never going to fly there

I got to where I needed to go quickly. There were no amenities. And the seats were painful.

They were only able to give me a seat and not my travel companion, she had to fly on a different airline. unacceptable

Stood inside the plane for more than an hour before take off

I never got an email for checking in for my flight back to Los Angeles so I got to airport extra early to sort it. they changed the gate, and so I had to run to the other end of the airport. Their app is wonky. They are not on WhatsApp and I didn’t have cell service to call for help. I think they need to up their game with communicating.

Inept company. Won't fly again with them if I can help it. Plane was the wrong size and they couldn't board 20 people.

On time, boarding was a little chaotic and with little information

More options for snacks or drinks ( taking in consideration that a lot of people suffer from Diabetes now days

To check in, it was horrible. their charges are outrageous. too many passengers, few people at the counters
