Travel confirmation is a document or notification that verifies the details of a travel booking. It typically includes essential information such as the flight number, departure and arrival times, hotel reservations, and itinerary details. This confirmation serves as proof of your travel arrangements and is important for check-in processes. Travel confirmations can be received via email, text message, or through a travel app. It is advisable to keep a copy of this confirmation handy, as it may be required at various points during your journey, such as at the airport or when checking into your accommodation.
