Long TSA lines this summer. The TSA is expecting long lines at their security check points during the busy summer travel season â especially when youâre traveling in the morning. The TSA recommends arriving at the airport at least 2 hours early for domestic travel and 3 hours early for international travel.
WestJet check-in and baggage drop closes 45 minutes before a domestic flight, and one hour before an international departure. We recommend guests arrive no later than 90 minutes prior to the departure of a domestic departure and two hours prior to an international flight. Be sure to plan extra time to get to the airport in case of traffic conditions or longer-than-expected airport lineups.
