Air cheat sheet: 10 terms, that you may hear on board

Let's check if you understand the meaning of the phrase:

“I bought open-jaw tickets to Argentina. A round trip cost $ 1,500. On the way back from Buenos Aires, there will be a layover in Paris. I've checked-in online for not to pip with overbooking.”

 This is a common slang for active travelers, using the terms "open-jaw", "round trip", "check-in", "layover" and "overbooking".
