So if I fly from Boston to Munich, I can fly nonstop on Lufthansa for about $1250 round trip. But if I want to go to Poland from from Boston, there are no nonstop flights, but I can fly a Boston-Munich-Krakow 1 stop flight that costs $1050 AND the Boston-Munich leg is literally the same flight numbers as those in the the above scenario. Okay, I get it: nonstop flights get to be more expense because no one likes stopovers. This isn't anything new to me. But what I've always wanted to know is -- if I really wanted to go to Munich as my final destination -- could I theoretically buy the $1050 Boston to Krakow ticket, and then just get off at Munich (and back on again there when returning)? I feel like there would be some kind of sneaky way the airlines would prevent this but I'm curious.
