The overhead bin did not stay down low enough so that I could place my bag in. It would lower then before I could place my bag raise slightly by a few inches. For someone of my height (5’5”) that was problematic. Fortunately another passenger saw my dilemma and held the bin lower to its full opening capacity. This also momentarily slowed down the boarding process.

Nothing, absolutely nothing.

The flight attendants were pretty much what I've come to expect on U.S. airlines--overweight, older, and sloppy in appearance. One of them looked like she had rolled out of bed ten minutes before arriving at the gate. It was the complete antithesis to the flight attendants on Hong Kong Airlines. Ah, for the good old days of air travel. Before the plane ever took off it was announced the the entertainment system on the seat back ahead of those in comfort seats was not working and wouldn't be for the duration of the flight. Having paid an additional $239 for the comfort seat in the hopes of making a 16-hour flight go by a bit faster, this was unconscionable. The food was far inferior to Hong Kong Airlines. In short, it was the trip from hell.

The crew was very friendly on board. The gate crew were a little curt, but it was a full flight and they were really trying to get everyone on board quickly so I can't be too upset about that.

Few entertainment options - direct TV unavailable for about half the flight, WiFi also unavailable for the same.

Aircraft seemed fairly new on inside, but didn't have power outlets. Small uncomfortable seats on a long flight that is almost always full.

The outbound crew was terrific. The flight itself was fine. We even arrived early.

Upon deplaning in Cancun, ALL passengers are put on a bus and driven far away from the terminals to an arrivals area. Those of us with connecting flights are royally f*cked at that point, especially if your connection is short, as mine was. The so-called shuttle to the departure terminals, which are entire kilometers away, was to arrive in like half an hour. HALF AN HOUR. Who has this time to spare?? The alternative to the shuttle is paying a taxi that charges a hefty fare--and God help you if you don't have cash. The departures terminal was swamped and only thru begging assistance and line cuts did I make my connection...and then only by the skin of my teeth. It was a complete nightmare.

We did get to our destination.

Flight was late, as always. I couldn’t sit with my spouse. Rows are so tight, one can barely get in/out and we are smaller than normal size. Baggage fees make overhead compartment loading a real nightmare. I wonder what they will think of next to make flying an even more terrible experience.

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.

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.
