Where it stands: A little vacation after a year stuck at home seems like a simple enough indulgence, but the travel industry is still facing some significant hurdles. Airlines: "It's not like pilots can just flip a switch. And they throw the keys at us and we come back to work, right?" Air Lines Pilot Association President Joe DePete said on the Axios Re:Cap podcast. "There's a lot involved in that. There are security aspects, there are training aspects, there are medical aspects." Rental cars: Rental companies sold off most of their fleets during the pandemic due to a lack of demand. And now a global chip shortage is squeezing the supply of new cars, making it hard for rental agencies to restock as demand increases. Not to mention, everything’s already booked: Hotels, campsites and Airbnb rentals are all hard to come by, especially in the most popular destinations.
