How to plan better flights
The cheapest ticket and the best ticket are often different. This is the routine we use before paying for a flight.
Key points
- Choose the best itinerary, not just the lowest fare.
- A single ticket protects you on a missed connection. Two separate tickets don't.
- Know your baggage and change rules before you pay.

1. Compare the whole itinerary
Look past the price. Check departure and arrival times, how long you'll wait between flights, and whether you land somewhere that is awkward to leave at night. An extra 40 euros for a daytime arrival is often money well spent.
2. Check the bag rules
Rules differ by airline and fare. Look at cabin bag size, checked bag allowance and weight limits before you book, not at the airport desk.
3. Leave room on connections
If you're on a single ticket, the airline has to look after you when a delay makes you miss a connection. If you're on two separate tickets, you're on your own. Allow a lot more time for the second arrangement, or don't do it.
4. Build in a buffer on the day
Aim to be at the airport well ahead of check-in closing. Traffic, queues and lost passports all show up on the worst possible day.
5. Read the change and refund terms
Know what happens if you need to change the date. Some fares allow it for a fee, and others don't allow it at all.
6. Confirm with the airline
After you book, check your reservation on the airline's own site and make sure the names match your passport exactly.

Seats and bags: decide on purpose
Pre-booked seats can be worth it if you're travelling with children or have a short connection and want to be near the front. If neither applies, leave it and take what you're given. For bags, buying your allowance online is nearly always cheaper than paying at the airport.
What happens when a flight is delayed or cancelled
Your rights depend on where you're flying from, which airline you're on and how long the delay is. In the EU and the UK, passenger-rights rules can require care and, in some cases, compensation. Elsewhere the rules are weaker. Keep your booking and boarding documents, write down what the airline tells you and check the official rules before you argue with a desk.
Choosing the airport and the arrival time
Land at a time when public transport is still running, and when your hotel can check you in. A 05:00 arrival that saves 30 euros isn't a saving if you sit on a bench for six hours.
