The carry-on bag policy is a bit unusual so I ended up checking the suitcase I’d typically bring as carry-on

Everything was fine except the flight was delayed an hour. No biggie. My only question is that I had a trip that passed through Isa to 3rd country. At check in I was informed that bags would go all the way through without re-checking in. Turns out bags had to be re-checked in at first entry to usa. I wish the rules were consistent and that all personnel knew the rules. Also united baggage track app does not work.

United baggage app does not work Personnel did not know baggage rules at Chck in.

Azul had a mechanical problem with the plane. It took them 6h to fix it. They made us wait for 6h which made mmost of the people lose their connection flight but azul voided to help anyone!

Knowing that GOL is an LCC, I was not expecting much. However, after realizing that every seat had the legroom typical of a Extra Comfort seat on NA carriers, I soon became won over. Regular recline functionality (missing on some of the larger LCCs worldwide) and a free drink and snack (also missing on many LCCs), TOO was truly a relaxing flight. 10/10. Would definitely fly again.

I mean, there was no entertainment available (to my knowledge) but there was allegedly Wi-Fi (I didn't try).

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,
