The travel Nerds have all sorts of opinions on when to get to the airport ahead of a flight, what sorts of upgrades or perks are most valuable to them — and of course, whether to check or carry on a bag. In this episode of Smart Money, the travel Nerds answer some lightning-round questions on their takes.

To send the Nerds your money questions, call or text the Nerd hotline at 901-730-6373 or email podcast@nerdwallet.com.
