Flights from the UK — Book Smart & Airport Guide
How to find the cheapest flights from UK airports, navigate terminals, understand hand luggage rules, and sort airport parking — all in one place.
🔍 Flight Comparison Sites
| Site | Best For |
|---|---|
| Google Flights (flights.google.com) | Date grid, price tracking alerts, “Explore” map for flexible destinations. Best overall research tool. |
| Skyscanner (skyscanner.net) | “Everywhere” search — find the cheapest destination on any date. Good for spontaneous trips. |
| Kayak (kayak.co.uk) | Hacker Fares (combining two one-way flights on different airlines), price forecasts. |
| Momondo (momondo.co.uk) | Deep OTA search — sometimes finds fares others miss. Good for long-haul. |
Golden rule: Use comparison sites to find the best price, then book directly with the airline. You get better customer protection (chargeback rights, easier amendments) and avoid third-party booking fees.

🎒 Hand Luggage Rules
Standard allowance (most full-service airlines — BA, Virgin, TUI, Jet2):
- 1 cabin bag up to 56 × 45 × 25 cm (including wheels and handles) — typically 10kg max.
- 1 small personal item (handbag, laptop bag) that fits under the seat in front.
Budget airlines:
- Ryanair Basic: Only 1 small personal bag (40 × 25 × 20 cm). Add Priority & 2 Cabin Bags (from £6–32 each way) for a 10kg cabin bag.
- easyJet Standard: 1 cabin bag (45 × 36 × 20 cm, no weight limit if you can lift it unaided). Add a large cabin bag (56 × 45 × 25 cm, 15kg) from £7.99.
- Wizz Air Basic: 1 small bag (40 × 30 × 20 cm). Add Wizz Priority for a trolley bag.
Liquids rule (all UK airports by June 2026): Most major UK airports have installed next-gen CT scanners and lifted the 100ml liquid restriction. However, always check your specific departure airport’s rules before packing — some smaller airports still enforce the 100ml rule. Containers larger than 100ml may still be rejected at security at airports without the new scanners.
