Booking directly with an airline gives you better flexibility for flight changes, upgrades, and loyalty points. Expedia is more convenient for comparing prices across airlines and bundling with hotels or cars. Which option is better depends on your priorities—flexibility versus potential savings. Some travelers book through Expedia for the deals, while others book direct for peace of mind. To decide which is the smarter option for your specific trip, call 866-204-0803 and get tailored booking advice.
