Do I need proof of an onward flight when checking in for a flight to Vietnam with an e-visa?

If you do not have a valid passport, arrange a replacement urgently: you will not be allowed to board a Vietnam-bound flight without one. Contact the airline promptly to ask about changing or refunding an existing ticket.

Travelers report that airline check-in counters are the most likely place to ask for onward-travel proof. Have confirmation of departure from Vietnam before your e-visa expires.

If you do not have a return ticket, check-in staff may scrutinize and retain a copy of your e-visa. Do not rely on unverified documents; use a valid visa and a genuine booking with matching dates.
