The airlines offering flights from the UK to Gibraltar are BA and EasyJet. Easyjet are offering flights from Bristol on the Thursday as well as flights from Gatwick. BA are offering flights from Heathrow. We also found that in some cases it was cheaper to book two singles rather than a return ticket, so that might be worth checking.

The nearest airports in Spain are Jerez and Malaga. The border queue between Spain and Gibraltar can sometimes be very long, depending on the level of political tension between Spain and the UK, so bear this in mind.
