7 Travel Documents You Must Pack for International Trips

5. Flight tickets and accommodation confirmations: Why print and digital both help

Airlines and immigration officers often ask for proof of onward travel and where you’ll stay while abroad. Keep printed copies of confirmed flight tickets and accommodation reservations, and save PDF versions on your phone. For visa applications, embassies usually want a travel itinerary and hotel booking confirmations showing your name and dates. If your tickets are refundable or changeable, note the terms so you can adjust plans without losing money. When staying with friends or family, obtain a printed invitation or proof of address to present if needed. If you booked through a travel agent or aggregator, retain the booking reference and any email confirmation that includes contact details. Having these documents readily available at check-in or at the border shortens queues and reduces misunderstandings.
