Flight Hacking DEN to LSC

You will need to either bring only a carry-on bag (highly recommended) or leave yourself plenty of time to go through security again. Flight hacking is completely allowed, but airlines don’t always tell you the cheapest way to get from DEN to LSC — but Champion Traveler does!
