While Vietnam Airlines does not operate direct flights out of Denver, it often partners with other foreign carriers or operates codeshare flights that may include Denver as a stopping point. When Vietnam Airlines passengers transit through Denver International Airport, they typically utilize the principal international terminal facilities, which are best geared to meet their needs. The indirect presence of the airline is made possible by a strong infrastructure and efficient customer service offered at DEN.

Vietnam Airlines travelers at Denver International Airport are usually served at the Jeppesen Terminal, the main international flight terminal. The terminal is renowned for its white, tent-like roof, which is an emblem of the Rocky Mountains covered with snow. Jeppesen Terminal has several international airline counters and is split into East and West sides. For Vietnam Airlines passengers, check-in and ticketing facilities are normally managed by airline partners or service counters allocated on the corresponding side of the terminal. Upon arrival at the terminal, passengers can locate the Vietnam Airlines check-in area either by signs or airport information services.

Vietnam Airlines ticketing at DEN is handled efficiently at the airport ticket counters. The counters can handle a range of passenger needs, from buying tickets to changing flights, seat upgrades, and special travel requests. Trained staff are available to help passengers in English and are familiar with the specific procedures required for Vietnam Airlines and its codeshare partners. If the passenger has made a booking online or through a travel agent, they can still go to the ticketing counter to confirm, get rebooking help, or experience issues with their itinerary. In peak season, it is advisable for passengers to check in early because the ticketing area might have high volumes of international passengers traveling.

Vietnam Airlines Terminal DEN is streamlined and made convenient by a mix of the traditional check-in counters and automated self-service machines, based on partner airline operations arrangements. Vietnam Airlines travelers are asked to arrive at the airport at least three hours before the scheduled departure time for international flights, especially if they have checked bags or require special services. At the check-in counter, travel document validation, showing boarding passes, marking baggage, and providing gate notices are assisted by agents. Frequent flyer elite customers or business travelers receive preferential check-in with reduced waiting time and convenience of travel.
