Carry-On for Vietnam: Hanoi to Ho Chi Minh City Packing Guide

The classic Vietnamese itinerary runs Hanoi in the north down to Ho Chi Minh City in the south, often with stops at Ha Long Bay, Hue, Da Nang, and Hoi An along the way. Flying domestically is the practical way to cover these distances, but cabin allowances differ by carrier, fare, route and aircraft. Check every segment before choosing a bag.

The Three Domestic Airlines and Their Enforcement

Compare the actual carrier, fare and aircraft for every domestic segment; there is no common 7 kg allowance across all three carriers.

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 the North-South Climate Gap

Vietnam stretches over 1,650 km from north to south. The climate difference between Hanoi and Ho Chi Minh City is genuine and requires a specific packing approach.

Hanoi and the north (November through March) can be surprisingly cool: 10–18°C, overcast, and damp. A merino wool base layer is the right tool here. Merino regulates temperature across a wide range, packs small, resists odour across multiple wears, and does not need to be washed every day — a real advantage when you're weighing grams. One packable puffer or mid-fleece layer handles the coldest Hanoi evenings.

Ho Chi Minh City and the south is tropical year-round: 28–35°C with high humidity. Lightweight cotton or technical-fabric tees and loose trousers or shorts are what you need. Nothing heavy.

The layering principle that keeps your bag under 7 kg: bring three to four lightweight cotton or linen items for the south, plus one merino base layer and one mid-layer for the north. When you're in Hanoi, you wear the layers. When you reach Ho Chi Minh City, the mid-layer goes to the bottom of the bag.

Shop at Hoi An and Hanoi Markets

Vietnam has two exceptional shopping spots that change the calculus of what to pack.

Hoi An's tailors can produce custom-made linen shirts, trousers, and dresses in 24–48 hours at prices far below Western retail. Arriving in Hoi An with space in your bag and leaving with two or three items you had made costs less than checking a bag on your flights home.

Hanoi's Old Quarter around Hang Gai street stocks good-quality cotton and linen clothing, silk scarves, and casual travel gear at low prices. If you arrive in January underprepared for Hanoi's winter chill, a 100,000–200,000 VND cotton scarf or light thermal layer is available within minutes of your hotel.

The strategy: intentionally pack a small amount of clothing, plan one or two market purchases, and keep the rest of your bag weight budget for toiletries and tech.

Ha Long Bay: Daypack as Your Main Bag

Ha Long Bay is a highlight of any Vietnam itinerary, but the cruise logistics require a specific approach. Wooden junk boats have narrow cabins, small wardrobes, and limited deck storage. Most reputable cruise operators actively recommend guests bring a small bag on board.

The standard approach that works: book Hanoi accommodation that holds luggage free of charge (nearly all hotels and hostels do this for active guests), pack a 20–25 L daypack with two or three days of clothing, your toiletries, and a camera, and leave your main carry-on bag at the hotel. You board the cruise light, navigate the boat decks easily, and return to Hanoi to collect your bag before flying south.

A daypack counts as the permitted small item only if it meets that category’s size. It shares Vietjet Eco’s 7 kg combined allowance; it does not create extra weight entitlement.

Navigating Vietnamese Cities with a Carry-On

Hanoi and Ho Chi Minh City are busy, traffic-dense cities most effectively navigated by motorbike taxi (Grab Moto) or tuk-tuk rather than car. A 40 L roll-aboard is manageable in a Grab car but awkward on a motorbike taxi or scooter.

If your bag is soft-sided and compressible, you can strap it to a Grab Moto without much difficulty. If it's a rigid roller case, stick to Grab Car or a metered taxi. Ho Chi Minh City's District 1 and Hanoi's Old Quarter are walkable from most guesthouses — a compact carry-on is a real advantage on narrow pavements shared with parked motorbikes.

Toiletries: Buy on Arrival

Vietnamese pharmacies, Vinmart supermarkets, and Bach Hoa Xanh convenience stores sell toiletries at 30–50% below Western prices. Pack a solid shampoo bar and solid deodorant for your first 24 hours, then resupply locally. There is no reason to fill your 100 ml liquids bag before you fly.
