How to Choose the Best Airline for a Long Flight
The best airline depends on your destination, budget, cabin, and personal priorities. Before booking, compare the total travel time, number of connections, aircraft type, seat configuration, baggage allowance, and onboard amenities.
A nonstop flight can sometimes be worth paying more for because it eliminates a connection and reduces total travel time. This is especially important when traveling from the USA to Asia or Australia, where flight times can be exceptionally long.
