Why International Flights Need More Time
International flights commonly require additional time for check-in, customs and immigration processes, and sometimes larger, busier airport terminals - the extended 3-hour guideline accounts for these additional steps not present on typical domestic flights.
When to Add Even More Buffer
Allow extra time beyond these baselines during holiday travel periods when airports are notably busier, at unfamiliar or particularly large airports where navigation itself takes longer, or when flying through security checkpoints known to run longer wait times than average.
