Nonstop Flights and Layovers

Travelers looking to fly from DCA to CMB can generally find a 2-layover flight. Because there is not usually a direct flight option the real-world direct flight time of 17 hour 3 minutes may not be realistic.


Flight Hacking DCA to CMB

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 DCA to CMB — but Champion Traveler does!

Hack #1: New York, NY (DCA > JFK > CMB)

  • Price for both tickets: $1003
  • Average savings: $73 (6.78%)
