I LIKE THE SERVICE ON BORD OF THE PLANE

Mediocre 3.3

The check-in staff were very friendly and helpful.

I already knew I was going to pay $200 to ship my boards back home (I wonder if golf clubs which are roughly the same size cost as much,) but when pre-purchasing through the app for an "oversized" bag you have to put a "one" in the checked bag and a "one" in the oversized bag even though they're the same bag, but then they charge you for two, and when you tell the check-in person that you only have one bag of course they can't issue a refund. No, they tell you that you get to call customer service when you return home.

Aircraft seemed shabby despite refresh of Comfort Plus, food was really mediocre. Steer clear of the Asian Veg option.

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 volume controls on the tv we’re pretty poor. Was either too loud or too soft with only 5-6 volume settings.

Flight was on time, crew was friendly, plane was clean, and boarding was painless and efficient. Food was served which was a huge plus. I appreciate having a choice of almonds for a snack.

Friendly crew.

Stuck in Denver because our flight was delayed so we missed our connection to Houston. Couldn’t get a hotel voucher because they are claiming a weather delay (which there was none).

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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
