My boyfriend and I are planning to travel Eastern Europe in late July-mid August. We are hoping to fly home from Bodrum, Turkey with Easyjet directly to Liverpool which is home. We would ideally like to fly out to somewhere in Bosnia-Herzegovina/Serbia/Romania/Montenegro/Macdeonia however I cannot seem to find a flight to any of these places. We would be willing to go pretty much anywhere in the UK for an outbound flight, such as London for instance. We are willing to spend about £150 max, we cannot really afford to go above this price. The nearest place I can find so far is Budapest, however this isn't really a great option as we'd then have to get a train to Serbia. Plus we have been to Budapest before so do not really want to go again.

Any help/advice would be much appreciated, thank you
