Recently when commenting on the Cost of Genealogy, I said that I didn't see myself travelling to Europe to do research due to the cost of travel.
Since I have programmed "Transylvania" as one of my News Topics at my customized Google News page, I learned this morning that there's a Budget airline in Europe called Wizz that has stops in London, England; Cluj, Romania; and Poland. The news article wasn't specific about cities in Poland, but Wizz Air has an English website, and they do stop in Warsaw. Anyone planning a trip in Europe might want to check out their routes - there are stops in France, Spain, Germany, Norway, Italy, and Greece as well.
London, Cluj and Warsaw would be the three main stops of any Family History trip I would probably make. Whether it was to do research, or just visit the locations my ancestors lived. I could do a round-trip from London-Cluj for 53.60 GBP ($109). Of course, I have to get to London. It's probably still not any time soon, but it's nice to know about a budget airline that stops in so many European cities.
