My first and last time flying Delta! Everything that could have went wrong, did in fact go wrong. We were re-booked on connecting flights different then the one we originally booked and weren't even notified. They have a Delta app, but it doesn't even work right. Unless you physically go to the gate to check to see if the flight is on time, that is the only was to find out if you are re-booked onto a different flight or not. I have never flown an airline that re-books you on a different flight when they feel like it. I wouldn't recommend Delta Airlines to my worse enemy!

6.0 OK

The crew was good and attentive

The management was horrible, if you already knew the pilot was working extensive hours you could have had another pilot on standby just in case... I'm sure it would have been a lot cheaper and less of an inconvenient for everyone on the flight...

LAX MSY
9.3 Excellent

The staff are fun and friendly. One of the hostesses stepped into the vacant seat where I was sitting and stepped back further when people where pushing by. We were almost cheek to cheek. The closest I've come to a cute bum in years.

The gratis food offering isn't healthy - those bread pretzels, versus the almond & tomato juice I had on the next flight, with ...can't remember the name.

Not great communication from gate or staff on board. Failed to provide adequate water. No ice on super warm flight. Just bad experience overall.

I purchased 2 tickets at the same time but did not find out that the seats were not together until we checked in at the airport. May be my fault but we had to pay extra to occupy Emergency exit seats in order to sit together. May want to send reminder about check-in policy prior to flight or after tickets are purchased. Also mention the luggage fees.

LAX MSP
3.6 Mediocre

We were an hour late taking off because the pilot waited for a late passenger causing us to miss the take off firm which I feel was unfair to the entire plane who all boarded on time.

DFW PVR
8.0 Good

Flight attendant tried to stop from going to the bathroom prior to closing of the door. After going to the bathroom the door was closed 10 minutes later.

SFO MSP
7.6 Good

hard seats - no lumbar support - very uncomfortable!

MCO MSP
8.6 Excellent

boarding was easy and fast, crew was friendly and prompt

Had an aisle seat and the space for storing bag underneath was tight and smaller than the other two seats. Unfortunately, peanuts or pretzels would be appreciated when flights are four hours long. Rough landing - pretty sure it was a newbie pilot, but will never know. Air did not reach the aisle seat adequately, felt nothing - was hot.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an email and someone from our team will get back to you promptly.
