Travel day may be a joyous day or a very stressful day depending on traveler’s preparation.
Just few important issues to pay attention to before your flight day:
Arrive at the airport at least 304 hours before your flight time (for international trips), 2-3 hours before for domestic flights-to avoid risk of missing your flight and ending up delaying your trip and /or paying a lot of money at the same time to change your flight. Remember you need to give yourself enough time to wait inline to check in your bags, and to wait in another line to go through airport security . The earlier you are at the airport the smoother your trip is going to start.
Make sure your passport is valid at least for the next 6 months or more and that you have the necessary visa or documentation for your destination.
See if all vaccinations or medical documentations are ready for your travel.
Check to see if your hotel is booked for transit or otherwise.
Call or email your travel agent or the airline at least 24 hours before your flight to make sure no major change has happened to your flight that you may have missed.
