We have been on 6 flights over the last 8 days, all with Delta and we have already started telling people how wonderful the service was. Sherry on this last flight was amazing, working so hard all by herself as our flight attendant. We were very impressed. And the pilots all came out to say goodbye and thank you. All very nice...esp for me who needed some wheelchair assistance. We will certainly fly with you again in the future.

Smaller plane but ok for short flight

Even though I was disappointed by not being able to get the boarding passes from Delta for Aeromexico’s connecting flight to Bogota, I had an agent greet me after customs in Mexico to issue the boarding pass so I could use the transfer flight line. Excellent service throughout the entire trip.

Confusion over my boarding pass at the Delta terminal in Detroit.

The staff were fine, nothing really great, but nothing bad either.

So, we'll start with boarding. Why airlines can't figure out to board the plane from back to front is beyond me. No, let's load front to back so everyone has to uncomfortably shove past the people who have already taken their seats at the front of the plane. Then you get back there and all the overhead bins are full because everyone takes as many bags as possible onto the plane. Then you have to sacrifice the already tiny amount of foot room, "to put the bag fully underneath the seat in front of you." At this point you should be fine, except if you're over five and a half feet tall (I don't know if that's true I'm 6'2" and 275 lbs,) because then your knees are going to be buried so deep in the chair in front of you that the person up there doesn't even need a seat they can just sit on your knees. Luckily for you tall people, they put a nice metal rod just about knee level to really dig in and cause pain . . . Yay! Being a big guy, you try to be considerate and fold your arms in to give the person next to you as much space as possible, but don't expect that back as they'll spread out and become as wide as possible. Then to distract yourself from the discomfort, you try to use the free in flight entertainment via the United app, but "it's not available right now." In summation either be short and small or be rich and buy the seats with extra legroom when you fly United.

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

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 the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes 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 can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals 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.
