Booking flights when moving abroad means more than finding a cheap ticket. Here's how to find better fares, avoid baggage charges, and fly with your family without paying more than you need to..

When to Book Flights When Moving Abroad
There's no perfect day to book, whatever you've heard. Flight-deal site Going suggests booking international flights two to eight months ahead, and earlier for school holidays and Christmas.
Expedia's 2026 data found Sunday the most expensive day to book, but the difference is small. Being flexible on your travel dates saves far more than picking the right day.

How to search
Start with a comparison site like Skyscanner or Google Flights. Search a whole month rather than fixed dates, because moving your trip by a day or two can cut the price. Set a price alert on your route so you're told when fares drop.
Before you book, check the airline's own website too. It's sometimes the same price or cheaper, and changes are easier if your plans move.
If a booking site offers to charge you in pounds instead of the local currency, say no. The exchange rate is usually worse. And use a card with no foreign transaction fees.
Baggage When You're Moving
When you're moving abroad, baggage can cost more than the ticket. What you can take depends on the airline and the fare you book, so compare the total price with bags included, not just the headline fare.
Check the allowance for each person, including children and infants, and the weight limit for each bag.
Add extra bags online when you book. It's much cheaper than paying at the airport.
Weigh your cases at home before you leave.
If you're taking a lot, compare the cost of excess baggage with shipping your things separately.
Flying With Family
Flying with children takes more planning, so sort these before you book.
Seats together: some airlines charge to choose seats, even for families. Check the airline's policy and book seats early if you need them.
Babies and toddlers: children under two can usually fly on your lap, but they often still pay a fare or taxes. Ask about bassinet seats on long flights, as numbers are limited.
Pushchairs and car seats: many airlines let you take these free, but the rules vary. Check before you fly.
Passports: every child needs their own passport, and some countries need it to be valid for several months after you arrive. Check the entry rules for where you're moving.
Long-haul tip: night flights can make a long journey easier for younger children.
Questions People Ask About Flying Abroad
How much baggage can my family take when we move abroad?
It depends on the airline and the fare you book. Each person usually has their own allowance, but infants often get less. Check the airline's baggage page for your exact fare before you pay.
Is it cheaper to ship my things or pay for extra bags?
For a few extra cases, extra bags booked online are often simpler. For lots of belongings, get a shipping quote and compare the two.
Should I book a one-way ticket when I'm moving?
If you're not coming back, a one-way ticket usually makes sense. Some countries may ask for proof of onward travel or a valid visa, so check the entry rules first.
Do my children need their own seats?
Children aged two and over need their own seat. Under-twos can usually sit on your lap, but on long flights a seat or bassinet makes it easier.
Can I take my pet on the flight?
Some airlines allow pets, but the rules depend on the airline and the country you're moving to. Many countries have strict entry rules for animals, so check these early.
When you land
Sort your phone before you fly. An eSIM lets you have mobile data as soon as you land, so you can call a taxi, message family and find your way without hunting for a SIM shop. Check your phone supports eSIM first. Airalo is one option.
