Airline reviews

Everything about this flight was good except for the very end when I reached my destination. Everyone from the tune to the wheelchair escorts were great with the case were great but I miss you with people at the check in this at the very end. I need help from the chicken desk because I forgot my pillow on the plane The female worker at the chicken desk said that they found my pillow and she was going to retrieve it for me. She left a 30 minutes without any update and her so she saw me walking back and forth waiting for her and they didn't even bother calling her or radioing her for any updates. They were busy because they were behind schedule and they were overwhelmed but thanks because at least glanced me and try to give me an update just a quick radio check or phone call. I don't care about the pillow but if you tell me to wait, I waited for at least half an hour before I said something and I just left because they wouldn't bother talking to me so I could, so everything's going in the review. I took pictures of the two men that were left working at the check-in counter. The totally ignored me despite the signals I've been giving them. I don't see any offers in the kayak review to add pictures or screenshots so I'm going to post another review I don't know their name but I'm pretty sure Delta will find other names when they see the review. Google with pictures. There was another guy at the chicken counter bring an orange workers vest who finally left after telling me that the girl that was retrieving my pillow is working the gates now. That would have been if they just told me that's what happened. But I had no update. Make me wait for nothing. Thank you Delta airlines!

We had a great experience with Delta. They helped us from the start at the kiosk all the way to our final destination, including help reassigning and upgrading our seats free of charge at the gates, escorts with the wheelchair for my brother and even getting our luggage at baggage claim for us. I also had special help because I forgot my pillow on the plane. The wheelchair escort contacted for associates at the check-in desk all the way back to the plane and retrieved my pillow for me.

I am a Diamond Medallion Delta traveller and this was a disappointing flight. They allowed half the flight to preboard before Delta One and Diamond Medallion. Once on the plane in my Delta Premium Select seat we were not given any welcome or greeting. Throughout the flight the flight attendant also did not make us feel any sort of special service or attention and even rushed us when she did bring us a snack to pick in the dark not even offering a light to look at what it was -- she was overall not helpful and not accommodating. for the extra cost of the seat it was honestly not a special experience this flight. heads up that even the warm cookies are now packaged. I ate nothing. There really was nothing that was special, stood out or exceptional. Luckily I mostly slept. But I was disappointed and question if I may try a different flight next time I go to Tokyo. The last few Delta flights have been less than great. which makes me very sad.

Crew was real good, flight was smooth and came in early.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

New high end luggage ruined/zippers broken, items missing. All happened on return flight from msp to mso. Do better! Not store bought luggage but high end personalized ogio custom embroidered luggage. Total slap in the face ontop of an extra luggage fee that took me 3 hrs on chat to resolve.

The internet that was free was terrible, the turbulence was pretty bad - uncontrollable I know.

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was old and thus the seats were not good. No cushion left whatsoever, and it all was a bit worn out.

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

Everything was great!! I had no problems!! I would fly Aer Lingus again! 🥰

From Rome to Dublin if you want any refreshments you have to pay for them, Not used to this as we typically get soft drinks and a little snack on a 3hour flight in the US.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

On time, only a little turbulence, very competent and caring attendants. Clear information.

Economy seats a bit small but other than that it was all good.

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.
