It’s always prudent to know the recommended arrival time before your flight departure. The correct time varies from airport to airport and country to country. A general rule is one to two hours before departure for domestic flights and two to four hours for international flights.
Always check before leaving for the airport to see if your flight is delayed or possibly canceled. Delayed and canceled flights lead to longer lines and you may need to arrive even earlier so as not to miss your flight or an alternate flight if required.
Important Tip! When possible, check-in online rather than at the airport, pay checked baggage fees online (you avoid lines and often save money), and use curbside baggage check-in to avoid long lines at airport counters.
