Maybe yes but also maybe not. Intra-european travel can be cheap but it can also be expensive. You can take a Ryanair flight and a local train to stay somewhere cheap for a couple days. But you can also take a expensive Lufthansa flight to stay in a big city where costs can be similar or higher to where where you are. It will always depend of where you are and where you'd like to go to.

My impression is that nowadays the UK has more cheap flight options than the rest of Europe and that trains aren't as cheap as they used to be a decade ago.
