Carry-On Only for Hanoi: Vietnam Airlines vs VietJet Bag Rules

Hanoi is Vietnam's capital — more formal and historically layered than the south, with cooler winters, tree-lined colonial boulevards, and a distinct food culture. It's also the gateway to Northern Vietnam's most dramatic landscapes: Ha Long Bay, Ninh Binh, and the mountain roads of Ha Giang. The key packing decision before you leave is which airline you're flying and how strictly they enforce the 7 kg carry-on limit.

Airline Quick Reference

Airline	Carry-On Limit	Max Size	Enforcement
Vietnam Airlines	7 kg	56 × 36 × 23 cm	Moderate
VietJet Air	7 kg	56 × 36 × 23 cm	Strict — sizer checks at gate
Bamboo Airways	7 kg	56 × 36 × 23 cm	Moderate
Vietravel Airlines	7 kg	50 × 40 × 20 cm	Moderate

VietJet vs Vietnam Airlines — Same Limit, Very Different Experience

VietJet Air offers the cheapest fares on most domestic routes and many international routes to Hanoi. The base fare is genuinely cheap. What VietJet makes back is on baggage fees — and the airline enforces its 7 kg cabin limit more aggressively than most carriers in the region.

At Noi Bai Airport (HAN) and on busy domestic routes like Hanoi–Ho Chi Minh City, VietJet agents use sizer frames and scales at the gate. Bags that don't fit the sizer are checked. The on-the-spot fee is significantly higher than pre-booking a checked allowance online. If you're on a VietJet flight, treat 7 kg as a hard ceiling.

Vietnam Airlines allows the same 7 kg in the cabin but enforcement in practice is lighter — particularly for bags that are marginally over or shaped slightly differently. Vietnam Airlines also has a better on-time record and a more predictable experience overall. For domestic connections from Hanoi to Hue, Da Nang, or other cities, the fare difference is often worth checking.

Northern Vietnam's Climate — Packing for Variable Temperatures

This is the most important packing difference between visiting Hanoi and visiting Ho Chi Minh City or Bali. Hanoi has four seasons.

October–November: Warm, dry, golden light — the best time to visit. 22–28°C. Minimal packing needs.

December–February (winter): Hanoi winter is real. Temperatures of 13–20°C are common, with cold fronts dropping to 10°C or below. The city feels damp and misty. A lightweight down jacket or packable fleece is not optional during this period — it's the difference between comfortable and miserable. This is the most common packing mistake made by travellers expecting year-round tropical heat.

March–April: Warming up, some drizzle, pleasant. 18–25°C.

May–September: Hot and humid, with heavy summer rains. 30–35°C. Full tropical packing — quick-dry fabrics, rain layer.

Check your travel dates and pack accordingly. Hanoi is the only major Vietnam destination where winter warmth is genuinely needed.

Packing for Ha Long Bay

Ha Long Bay overnight cruises (1–2 nights on the boat) are an easy extension from Hanoi. For the cruise itself, you need very little: swimwear, a light layer for the evening on deck (it can be cool even in warm months), sunscreen, and casual clothing for kayaking and island hikes.

Most reputable cruise operators run a shuttle bus from Hanoi and store your main luggage at their Hanoi office for the duration of the cruise. This means you only take a small daypack onto the boat — a liberating way to travel that makes the overnight cruise far more comfortable than dragging your full carry-on aboard.

Book a cruise that includes luggage storage in Hanoi. This is standard practice for operators running the 2-day-1-night or 3-day-2-night itineraries.

Ha Giang Motorbike Loop — Minimum Viable Packing

The Ha Giang loop in Northern Vietnam's mountainous northwest is one of Southeast Asia's great road trips. Most riders rent motorbikes (or hire an Easy Rider guide on a semi-automatic) for 3–5 days of mountain roads, rice terraces, and ethnic minority villages.

For the loop, leave your full carry-on at your guesthouse in Ha Giang town. Take only:

• A 15–20 L daypack
• 2 changes of lightweight clothing
• A packable rain jacket (mountain rain arrives fast)
• A fleece or down layer (mountain elevations reach 1,500 m — genuinely cold at night)
• Sunscreen, toiletries in small containers
• Phone charging brick

The motorbike provides no luggage storage beyond bungee cords on the rear rack. Overpacking makes the riding physically harder on mountain roads.

Cultural Sites and Dress Code

Hanoi's major sights include the Ho Chi Minh Mausoleum, Temple of Literature, Hoan Kiem Lake, and the Old Quarter. The Mausoleum has a strict dress code: no shorts, no sleeveless tops, silence required. Long trousers and a short-sleeved shirt satisfies the requirements. Temple of Literature is less strict but respectful dress is appropriate.

Pack at least one pair of long trousers or a long skirt for these sites. In Hanoi's winter, you'll be wearing them anyway.

Street Food Culture and What Not to Pack

Hanoi street food is exceptional and cheap. Bun cha, pho, banh mi, bun rieu — the city's Old Quarter has one of the world's great street food concentrations. None of this requires special packing. Eat as much as possible and bring nothing food-related from home.

Airport Tips

• Noi Bai Airport (HAN) is 45 km north of central Hanoi — allow 60–90 minutes by taxi or shuttle
• The Vietnam Airlines bus service from the city centre is affordable and reliable
• Currency: VND — ATMs at HAN offer reasonable rates
• VietJet check-in queues at HAN can be long on busy domestic routes; arrive with enough time to spare

Bottom Line

Hanoi rewards carry-on travel. The city is compact enough to walk or take a taxi across, Ha Long Bay operators store your luggage for the cruise, and budget carriers like VietJet are both the cheapest option and the strictest enforcer of the 7 kg limit. Pack to 7 kg, account for Hanoi's winter if your dates call for it, and travel light enough to make the Ha Giang loop possible without renting extra storage.
