Moving Abroad With Just a Carry-On: Expat Packing Guide

Relocating to a new country with only a carry-on bag is more achievable than most people expect. The strategy is simple: ship most possessions ahead, and carry only what is irreplaceable, legally essential, or urgently needed on arrival. This guide tells you exactly what to pack in the cabin and what to leave for the shipping container.

The Core Strategy: Ship First, Fly Light

Most expat moves involve a mixture of:

• Sea freight — slowest (6–12 weeks) but cheapest per kilogram for large volumes; good for furniture and books
• Air freight / courier services — FedEx, DHL, or UPS; 3–7 days, expensive but practical for one or two boxes
• National postal services — USPS International Priority Mail, Royal Mail, La Poste; good value for boxes under 20 kg

Book your shipment 4–8 weeks before your flight. Most countries have duty-free allowances for household effects when you are establishing official residence — research the customs rules for your destination country before shipping.

What Must Travel in Your Carry-On

These items cannot be shipped, checked, or sent ahead:

For medications, bring a letter from your doctor listing your prescriptions and dosages. Some countries require a translated or notarised version — check requirements for your destination.

What to Ship or Buy at Destination

Airlines With Generous Carry-On Allowances

If your expat move requires a one-way transatlantic or long-haul flight, pick an airline with a higher carry-on weight limit:

For most expat moves, economy class on a full-service carrier with a free checked bag is the most practical option. A generous carry-on allowance matters when you also check one bag.

What a Two-Week Carry-On Holds

A standard 40 litre carry-on bag can fit:

• 7 days of clothing (mix-and-match, travel fabrics)
• Toiletries bag (all under 100 ml or transfer-size)
• Laptop and charger
• One pair of shoes beyond what you're wearing
• Documents folder

A personal item (laptop bag or daypack) adds:

• Laptop or tablet if not in the main bag
• All official documents
• Medications
• Valuables

This setup genuinely covers the first two weeks at a new address while you wait for shipped boxes to arrive.

Day-One Purchases at Destination

Plan to buy these immediately after arriving — they are not worth the cabin space:

• SIM card or local phone plan (buy at the airport or a mobile store)
• Laundry detergent and cleaning supplies
• Pillow and basic bedding (if accommodation is not furnished)
• Grocery staples for the first week

With a well-planned carry-on and shipment strategy, most expats find the move-in period smoother than expected. You arrive with everything critical close at hand, and the boxes follow within a few weeks.
