Vietnam Domestic Flights in 2026: Baggage Allowance, Check-in Tips, and Airline Comparison

Vietnam Airlines is the only full-service carrier that includes a 20kg checked bag on every domestic fare, along with a 7kg carry-on. Bamboo Airways historically matched that allowance—20kg checked plus 7kg carry-on—but the airline went through restructuring in 2024–2025, so before booking in 2026, confirm it still operates your route and hasn't changed baggage rules.

VietJet Air and Pacific Airlines are the budget options. VietJet's base fare includes only a 7kg carry-on; some 'Eco' fare buckets now exclude even that, so read the fare rules before paying. Prepaid checked baggage (20kg) costs roughly VND 250,000–350,000 online, but double that if you add it at the airport. Pacific Airlines, now owned by Vietnam Airlines, runs as a separate low-cost brand and charges similar fees for checked bags.

In the air, differences shrink. Hanoi to Ho Chi Minh City is about 2 hours; Hanoi to Da Nang about 1 hour 20 minutes; Da Nang to Ho Chi Minh City about 1 hour 45 minutes. Full-service fares often include a small snack, but on these short sectors the seat pitch and departure time matter more than the sandwich.

On VietJet Air and Pacific Airlines, a 20kg checked bag costs around VND 250,000–350,000 (US$10–14) when you prepay online, but the same bag can cost double if you pay at the airport check-in desk. Vietnam Airlines and Bamboo Airways include a 20kg checked allowance in most domestic fares, plus the standard 7kg carry-on. If you fly VietJet or Pacific, always buy baggage online at booking or at least 24 hours before departure; do not wait until you reach Noi Bai or Tan Son Nhat.

Weight limits matter. Low-cost carriers enforce them strictly, and a bag that is 1kg over can trigger an excess fee. Don't assume a small overage will be waved through. For 2026, check exactly what VietJet's Basic/Eco fare includes: some low-cost fare classes have removed the 7kg carry-on allowance entirely, leaving only a small personal item. If you need a carry-on suitcase, book a fare class that includes it or add it separately.

Prepaying baggage is not just cheaper—it's also faster. At the airport, the excess baggage counter is usually separate, and queues during morning and evening rush hours can eat 20–30 minutes. When you check in online and have already prepaid luggage, you can head straight to bag drop. For international connections through Hanoi or Ho Chi Minh City, confirm whether your domestic ticket's baggage is through-checked to the final destination; if not, you'll need to collect and recheck.

Domestic check-in counters at Noi Bai and Tan Son Nhat close exactly 40 minutes before departure, and online check-in opens 24 hours ahead for all four carriers—Vietnam Airlines, Bamboo Airways, VietJet, and Pacific Airlines. If you have not checked in by the 40-minute cutoff, you will be denied boarding even if the aircraft is still at the gate. Complete online check-in as soon as it opens, then save the boarding pass to your phone's wallet or take a screenshot; you do not need to print it, though paper copies are still accepted at security.

Arrive at the airport 2 hours before a domestic flight if you are only carrying hand luggage. Add another hour—3 hours total—if you are checking a bag or connecting to an international flight. At both Noi Bai (Hanoi) and Tan Son Nhat (Ho Chi Minh City), the domestic terminals are in separate buildings from the international terminals. Walking between them can take 15–20 minutes, plus security and immigration, so allow at least 3 hours for any international connection booked on a separate ticket.

International visitors only need a passport for domestic flights; no visa or additional ID is required. Keep your passport handy for ID checks at boarding. If you checked in online and have no bags to drop, you can head straight to security with your phone, but be aware that gate closures typically happen 15–20 minutes before departure.

Vietnam Airlines and Bamboo Airways routinely price one-way Hanoi–Da Nang tickets at VND 1.5–2.5 million (US$60–100) when booked 4–6 weeks ahead, while VietJet and Pacific Airlines list fares from VND 400,000 (US$16) on the same route. The lowest fares almost always appear on each airline's official website or app, not on third-party booking platforms. Agents frequently add VND 100,000–300,000 in service fees, and their promotional prices are often stripped-down base fares that no longer exist on the airline's own site. Download the VietJet Air, Vietnam Airlines, and Bamboo Airways apps and check their fare calendars before buying anywhere else.

Timing matters more than fare alerts. During Tet (late January–February 2026) and the June–August school break, one-way Hanoi–Ho Chi Minh City fares can jump to VND 3 million or more, and seats sell out weeks in advance. For travel in those peaks, start checking prices 3 months out and buy as soon as you see a fare within your budget. For off-peak periods, 4–6 weeks ahead is usually enough; waiting until the last 7 days rarely saves money and often doubles the price.

If you compare only the headline fare, low-cost carriers look unbeatable. But a VietJet or Pacific Airlines base fare of VND 400,000 includes no checked bag and may even restrict carry-on size depending on the 2026 fare class. Prepaying 20 kg of checked luggage online costs around VND 250,000–350,000 (US$10–14); paying at the airport can double that. Add a seat selection fee and a 7 kg carry-on upgrade, and your VND 400,000 ticket quickly becomes VND 1 million or more. Before booking, add baggage and any extras on the official site, then compare that total against Vietnam Airlines or Bamboo Airways, which typically include 20 kg checked luggage. The gap is often much smaller than the base fares suggest.

At Tan Son Nhat (SGN), domestic flights use Terminal 1 and international flights use Terminal 2, a 500-meter walk or a free shuttle; at Noi Bai (HAN), Terminal 1 handles domestic and Terminal 2 handles international, with a free shuttle running every 10–15 minutes. Because you must change buildings and clear security again, allow at least 3 hours between a domestic arrival and an international departure—2 hours is risky if you have checked bags.

If both your domestic and international legs are on a single Vietnam Airlines ticket (or a SkyTeam partner), Vietnam Airlines can often through-check your baggage to the final destination, so you won't need to collect and recheck it during the connection. On separate tickets, even with Vietnam Airlines, through-check is not guaranteed; you will usually need to pick up your bag in the domestic terminal, exit to the international terminal, and recheck it yourself. Note that many budget fares on VietJet Air and Pacific Airlines include only a 7kg carry-on bag, so if you need 20kg of checked luggage, prepay online for VND 250,000–350,000 (US$10–14); buying at the airport can double that. Bamboo Airways and Vietnam Airlines standard fares include 20kg checked luggage.

Pacific Airlines was being absorbed into Vietnam Airlines by 2026; if your ticket still says Pacific, confirm whether the flight is actually operated as Vietnam Airlines (and thus follows VN through-check rules) or as a separate low-cost operation. Before booking a separate-ticket connection, call the airline or check the e-ticket conditions to confirm whether bags can be checked through and what the minimum connection time is.

From May to October, central Vietnam's rainy season regularly delays domestic flights at Da Nang, Hue, and Chu Lai. Afternoon thunderstorms are the main culprit, so book departures before 10:00 if you're connecting to an international flight or have a fixed schedule. Morning flights in Vietnam still get delayed, but the buffer is usually shorter. If a storm cancels your flight, Vietnam Airlines and Bamboo Airways rebook you on the next available seat; VietJet and Pacific Airlines tend to offer a refund or a later flight, and getting cash back can take 2–4 weeks. Arrive at least 2 hours before a domestic departure—counters close 40 minutes before takeoff.

When you prepay checked baggage on VietJet or Pacific Airlines, keep a screenshot or PDF of the payment confirmation. Airport staff occasionally ask for proof at check-in, especially at smaller airports like Phu Quoc or Nha Trang, and a paper or phone copy avoids a VND 250,000–350,000 charge for a second bag. Before booking Bamboo Airways in 2026, confirm on their official website that they are still operating the route you need; the airline went through restructuring in 2024–2025 and some frequencies were cut. Finally, check VietJet's current fare class: the cheapest 'Eco' tickets sometimes restrict carry-on to one small personal item under 7kg, and dimensions are enforced at the gate with a metal sizer. If your bag doesn't fit, you'll pay gate-check fees of VND 350,000 or more.
