Boarding was very delayed. The flight was very delayed. There was never an explanation or acknowledgememt, of the delay and it seemed no effort to make up the delay while in the air. As a result, a great number of us missed our connections to Boston. Poor effort by AeroMexico and Delta

We flew for only 45 minutes on a flight that had been scheduled for 1.3 hours.

The long delay seemed strange, as the plane had arrived from Costa Rica. Why would an airline schedule the same plane for an international flight and then a short hop from Newark to DC without adequate time in between? The departure gate at Newark was absolute chaos! Announcements were overlapping and not understandable. There was inadequate seating.

Entertainment and crew were great- comfortable seats, got to watch a couple of movies with headphones provided by Delta; forgot mine so I assumed I would be miserable thru the whole 4 hour flight. so glad I was wrong! Would definitely take another flight with Delta... looking into the frequent flyer program as we speak

Flight crew was good, we arrived early on flight out and back! Feel like seats are tinier than ever, maybe it was just me. Food (water & pretzels) were OK, but nothing special (then again it was a short flight, so I didn't expect anything). Plane was small so we needed to gate check bags and the gate attendant came around and tagged everyone's bag for us, well before boarding which was hugely efficient - kudos to her on that!

Gate attendant's mic was broken (or she didn't know how to use) so she had to yell into the boarding area.

Fairly new airplane seats with TV screens, USB slots, complimentary headphone.

Flight was moved 6 hours with no explaination a few weeks before (apparently there's an on going strike), so we had to pay to switch our connecting flight. The day of, there was a 2hr delay so we missed our connecting flight. Food was ok. Drink selection was mediocre. Very limited TV and movie selection. Probably should have stuck with my instincts to fly with a larger carrier.

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.
