I was returning from an international flight, and had carried my smallish rollerboard +1 personal bag all through (including outbound) with no problems. Just on the last leg, IAD to RDU, the gate agent forced me to check the bag, even though the flight was not full, and the bag could easily fit in the overhead bin. I was in Group 3.

Forced to gate check rollerboard for no reason.

Customer service at the airport after our flight was canceled was the only thing hat made my experience better. Thankfully she was able to find me a flight with American to get home to my family.

I was headed to see my family because my grandmother passed away that morning. You changed our gate 10 minutes prior to boarding, so ALL of the passengers left the gate, boarded the airport tram, went to the other side of the airport to arrive at our gate to find out 30 seconds after walking up that YOU CANCELED OUR FLIGHT?!!!?!! And then automatically scheduled us all for a flight at 10pm that night. Not ok.

Boarding and disembarking were quite painful with an overcrowded plane and most passangers carrying on huge bags. What happened to shoulder bags only for carry on?

One of us had the last seat on the plane even though they were reserved almost a month ago. However we had signed up for basic economy so that was not a shock. What was a shock was that water was dripping from the top side track onto his lap and he had to use the provided brochures to redirect the dripping water. The steward said it was condensation and that was it. Also, since it was next to bathroom, the smell wasn't great and the small child screaming while waiting to get into the bathroom wasn't pleasant.

Nothing

I never got to Cabo. It took 2 hours for Delta to de-ice the plane in Milwaukee. Because of the long delay we missed the flight to Cabo. We asked Delta to book us on another flight to get us to Cabo today, Delta reps said nothing was available. Delta gave us a discounted coupon for a hotel in Atlanta and rebooked us on a flight to Cabo tomorrow.

On time flight arrival

Baggage Claim was very disorganized. They indicated bags were to be picked up at a carousel that was under construction. When we went to the service desk, they directed us to another carousel which was incorrect. There was no announcement made and there was a delay in updating the baggage claim board.

Love the free movies and individual screen, and the new seats are more comfortable

That it wasn’t 1970, with full meals and more leg room

We were upgraded to seats with more room. After a 8+ hour flight before this one, it was welcome. We had to deal with the hurricane. After delays, the pilot filed a different flight plan. The gate people kept us updated and you had the feeling they were trying to get us to our destination. We left a couple hours late and had a very skillful landing into some pretty stiff winds but landed safely.

I could upgrade to a good seat closer to the front. And I was the only one in my row maybe because people had canceled their flights. lol boarding was quick and simple. Good amount of over head space and room. Def easy going simple and had no issues

We only got cups of room temperature water I had to ask for ice and one passenger during boarding was on their phone being disruptive and loud and no one asked him to be quiet seeing as everyone was visibly annoyed.

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.
