The 3-1-1 rule on Expedia primarily refers to the TSA’s liquid carry-on regulation, which applies to flights booked through Expedia just as it does with any airline. Many travelers booking flights, hotels, or vacation packages on Expedia often come across this rule while preparing for airport security and wonder how it affects their journey.
