This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

The flight crew was friendly. I tried to adjust my seat online ahead of time but no option existed without additional fees. My friend asked at the gate about a seat change and was able to make it happen. That was great! The flight crew moved a very tall gentleman and his companion which allowed us to have more space which was nice. Overall, good experience. Appreciated the blanket and pillow.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

Our seats were comfortable with adequate room to stretch out and recline. The food was tasty and served it just the right intervals. Our flight attendant was extra attentive and friendly. Flight arrived early. And the most turbulence. Overall that’s good and experience for an 11 hour flight as can be hoped for

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

There was a slight delay. Otherwise, everything else was satisfactory.

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

The plane was known to be late in advance of takeoff. My guess is that it was known to be late at 11am or 5 hours before scheduled takeoff time. We were late to leave and with a wheelchair and the a cart, we only made it to gate. We raced! Inside plane, all was great

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.
