Cons: "Choice of healthier snack"

Cons: "Seats are so small. Flight was delayed."

Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"

Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."

Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."

Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."

Pros: "Most comfortable flight I have taken in some time. Spacious seat, power, good entertaiment, attentive flight crew. On time. Not usually a Delta flier, but times and destination made Delta the choice. Turns out a great choice."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Crew was the best!"
Cons: "I really dislike the snack boxes. Snacks need to be more like a small sandwich or grapes, cheese and nuts. Not all that packaged stuff."

Pros: "Boarding super excellent! Also: Best landing I've ever experienced! Props to the pilot!!"

Pros: "Newer plane with movies."
Cons: "Airlines pack you on so tight."

Pros: "Excellent crew and comfortable flight"

Cons: "Nothing."

Pros: "Great,I loved it!"

Cons: "No entertainment system, no power outlet...for first class this is disgraceful"

Pros: "The flight crew was great"

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Pros: "Excellent customer service. That doesn't seem to happen too often with airlines. Delta has been outstanding."
Cons: "No complaints."

Pros: "Yes made sure mask was in place"
Cons: "No"

Pros: "I used frequent flyer miles for the tickets."

Cons: "Overbooked and crowded, on a Sunday."

Pros: "Crew was nice"
Cons: "Lots of empty seats... during covid/social distancing there should only be 2 ppl in a row especially if there is room...it was crowded and not consistent with signs posted saying stay 6 ft apart"

Pros: "The boarding process was not complicated and my moved along in an orderly fashion."

Pros: "Just about everything was wonderful. Flight crew was great, infotainment centers are always a plus, and the seats are better than I remember (don’t get excited, slightly)."
Cons: "This was considered an international flight, as we discovered when we were directed to the international terminal. It was also a 6 hour flight so... where was the food?! We could pay upwards of $10 for 3-4 options, none of which were 100% kid friendly. What’s up with that?"

Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."

Pros: "Pilot made up time so we made it in early!"

Pros: "The helpful steward"
Cons: "The bumpy ride"

Pros: "Crew was nice and friendly. Pilots flew great. We arrived a few mins early as well."
Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."

En el aeropuerto de Denver habia solo dos personas en el securty check por lo cual la demora fue involuntaria en mi caso. Cuando estoy haciendo la fila para ingresar al avion (esyando en la misma cola antes de ingresar) me informanque no podre embarcar..(claro ya habia designado mi billete a otras personas. pesima atencion y pesimna experiencia con los empleados de ese vuelo.

Pros: "Entertainment modules in cabin were nice"
Cons: "Forced to check my bag in at the gate. Upon completion of boarding, there were several empty spaces in the overhead bins, and my bag could have fit easily. Upon arriving in Houston, baggage claim was VERY slow. Small flight of less than 30 people. Southwest had 3 flights arrive and complete baggage claims by the time our bags became available. Airport personnel confirmed that it is typical or normal for American because they operate with a small "skeleton" ground crew. Flight arrived just after 11:20pm,, but wasn't able to head out for transportation until after 12:30am. VERY upset and disappointed with service."

Pros: "Friendly service"

I drive 3 hrs o the airport and I did not want to drive back or wait 3 days for a lost bag to be sent to me as I have before.
