Carry-On Only for Vietnam: Airline Rules and Packing

For travel between Hanoi, Da Nang and Ho Chi Minh City, plan baggage against each booked segment. Vietjet Eco includes 7 kg combined, while Vietnam Airlines uses different route and ticket conditions.

Know Your Airline's Enforcement Level

Three carriers operate most domestic routes in Vietnam:

Vietjet VJ Eco includes a 56 × 36 × 23 cm main bag and one permitted small item within 7 kg combined. Obtain the required cabin label at check-in. Staff may recheck size and weight at the gate; noncompliant baggage may require payment or be refused. No measured inspection frequency is established.

For Vietnam Airlines tickets issued or exchanged on or after 5 May 2025, Economy uses one main bag up to 10 kg plus one accessory sharing 12 kg on US/Australia/Europe (including Russia) routes, or 10 kg on other routes. Main bag: 56×36×23 cm and 115 cm total; accessory: 40×30×15 cm and 85 cm total. ATR72 has a 7 kg cabin total; earlier tickets differ. Confirm the booked route, aircraft and ticket date.

Bamboo Airways Economy allows one main bag and/or one permitted small personal item within 7 kg combined. The main box is 56×36×23 cm, with a 115 cm total. One ordinary small item uses 30×20×10 cm, or a laptop bag 40×30×10 cm; both share the cabin weight. Business allows two main bags and/or one permitted small item within 14 kg combined, each main bag at most 7 kg. The main bag must be weighed/tagged, with the published online-check-in exception; the small item needs no tag. Confirm the actual booking and do not infer a measured inspection frequency from the airline’s market position.

Packing for Vietnam's North-South Climate Gap

Vietnam stretches 1,650 km from north to south and has dramatically different climates. If your itinerary runs from Hanoi in winter down to Ho Chi Minh City, or vice versa, you need to pack for both:

North (Hanoi, Sapa, Ha Long Bay) in winter: Expect 10–18°C, damp, and grey. A lightweight down jacket or a packable puffer mid-layer is useful. Merino wool base layers are ideal — warm, light, and wearable multiple days.

Central (Da Nang, Hoi An): 20–30°C depending on season. Light layers.

South (Ho Chi Minh City, Mekong Delta): Tropical. 28–35°C year-round. No jacket needed.

The layering strategy: pack light base layers and add/remove the one mid-layer you've brought. Do not pack separate winter and summer wardrobes — they won't both fit in 7 kg.

Airport Security in Vietnam

Security at Hanoi Noi Bai, Da Nang, and Ho Chi Minh City Tan Son Nhat is thorough. Laptops come out. Liquids must comply with the 100 ml rule in a clear bag. Shoes are typically x-rayed but do not always need to be removed — follow the agent's instruction. Allow 75 minutes before international departures and 60 minutes before domestic ones at Noi Bai and Tan Son Nhat.

Da Nang airport is smaller and faster. Security at Da Nang is efficient.

Toiletries Strategy

Vietnam's pharmacies, Vinmart supermarkets, and Bach Hoa Xanh convenience stores are stocked with toiletries at very low prices. Sunscreen, shampoo, body wash, and deodorant cost a fraction of European or Australian equivalents. There is no reason to fill your liquids bag before flying.

Pack solid alternatives for your first 24 hours — a solid shampoo bar, solid sunscreen stick, solid deodorant. Then resupply locally. This strips 400–600 g from your bag before you even land.

Motorbike Helmets: Rent at Destination

Renting a motorbike is one of the great experiences of Vietnam — Hanoi's Old Quarter, Da Nang to Hoi An, the mountain roads of Ha Giang. A motorbike helmet is required by law and cannot fit in a carry-on bag. Do not try. Helmets are available for rent or purchase everywhere motorbikes are hired. Budget around 20,000–50,000 VND per day for a helmet rental.

Ha Long Bay: The Small Bag Strategy

Ha Long Bay overnight and multi-day cruises use wooden junk boats with limited cabin storage. Most cruise operators recommend passengers bring only a small bag on board. The standard approach:

1. Book accommodation in Hanoi that holds luggage (most hotels and hostels do this for free)
2. Pack a 20–25 L daypack with two days of clothing, toiletries, and a camera
3. Leave your main carry-on at the Hanoi hotel
4. Enjoy the cruise without hauling your full bag onto a boat deck

This makes the Ha Long Bay experience significantly more comfortable. Tight boat cabins, communal dining areas, and kayak transfers are all easier without a 40 L carry-on.
