I don't think most people know this, but if you are travelling in Europe and your flight is delayed or cancelled, they have to pay you additional compensation. According to an ad in the Chicago Sun Times, there is a law firm looking for American citizens who have been delayed or cancelled in their flights while travelling through Europe, probably for some type of mass lawsuit. The number they gave in the ad is 1-888-551-9944, if anyone on here had a flight cancelled or a lengthy delay recently. Best of luck!
