Just looking at a winter getaway and found some cheap flights from Southend Airport in February. You may need to play around with the dates and click on 3 week view but a quick example is Southend - Lanzarote @ £27.83 on the 6th of Feb and return on from Lanzarote - Southend @£12.83 on the 24th of Feb, total for £40.66. Used Southend plenty of times and voted best airport by WHICH for the 3rd year running. Not just Lanzarote but plenty of destinations in the new year at good prices. Get in quick as price will go up on demand.
