The cabin crew provided the most information out of the entire experience and were extremely friendly. I appreciate Dawn in particular. The lounge is nice when it is not so over-crowded. I appreciate some complimentary minor snacks and drinks; it certainly helped with the delay. What would normally be sufficient seating and power outlets became people tripping over each other with delayed flights.

The lounge staff were hard to find and not communicative about delays. The board only had 1 update to my departure time, which was 30 mins after the originally scheduled time, and did not update again until 25 minutes after that second time had passed. The lounge staff did not make an announcement until after that board update and even then the information was wrong. The one time I found someone to ask a question to, I was given the same information. I had no idea why there was a delay or what to expect and no way of finding out. It made coordinating next steps upon my arrival to my destination extremely difficult. The lounge is not particularly well-equipped for multiple delayed flights.

Good clean aircraft. Fairly comfortable seats. Even had a power outlet in my row. Not too bad for an aircraft from the late 70s.

for some reason, i had to pay to gate check a bag. It didnt seem like anyone else did while boarding my flight.

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.

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.

Arriving and calling someone to help me with the wheelchair was good. The women were so friendly and helpful. But when you're "stuck" in a chair and I arrived early, it would be nice for someone to check to see if you had to go the washroom. And I had to flag someone down to get me to the aircraft. No one came by and offered. But overall fantastic experience. I would fly porter again.

Wish their was more food on the flight. Even though it was a short one.

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.

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.
