- Cheapest months: January and February, cold but quiet
- Avoid: July and August, when it is 30°C and very humid
Before you book
- Low-cost carriers sell the seat and charge for the bag. Add £25–£45 each way for a checked 20 kg bag and the comparison changes.
- After 22:00 the airport buses are sparse, which makes a pre-booked transfer the cheaper option.
- Package protection is not automatic. Two bookings, two sets of terms, and ATOL cover becomes whatever each seller states.
