Travelling from Northampton originally, so can get to Birmingham or London easy, as well as midlands airports.
Want to go to Brussels first, then Amsterdam a few days later, then Dusseldorf, then Berlin and back home, all within a couple of weeks. However, flights not necessary between Dusseldorf and Berlin, may hike for that one!
Any suggestions on where to get cheap/decent flights from? Not sure out of all the flight places available!
