Nonstop Flights and Layovers
Travelers looking to fly from CPT to IAD can generally find a 1-layover flight. Because there is not usually a direct flight option the real-world direct flight time of 15 hour 15 minutes may not be realistic.
Flight Hacking CPT to IAD
Flight hacking is when you book two tickets instead of a layover, sometimes with different airlines. 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 CPT to IAD — but Champion Traveler does!
