If you are transiting through Doha and you have a long layover make sure you book the flight through Qatar airways and not using a code share that's a book through American airlines because they will deny you a STPC which is a stopover paid by carrier aka the free hotel. We ended up sleeping on the floor of the airport which kind of sucked but it wasn't the end of the world. Next time I will not make this mistake and I will never book with American airlines again.

If you're not in 1st class, you'll want a seat cushion. We were in comfort extra and both had sore tailbones. Seats very uncomfortable after a couple of hours.

You don't need to be there that early, an hour earlier than the departure for a local airport is fine.

  • I’m traveling with my family to Florida Keys. Which Key is the most kid-friendly?

    If you’re traveling with kids to Florida Keys, you’ll want to avoid Key West. It’s typically more crowded, and the nightlife is a bit noisier than the rest of the Keys. You can travel to Miami International Airport and drive to Key Largo to use as your base. If you don’t want to stay only in one spot, then from Key Largo you’re just a short drive from two other calm and worthwhile Keys—Islamorada (27m) and Duck Key (56m).
