Building on the trip trading capabilities, the birth of SkedFlex marks the beginning of the current Flight and Crew Management system.

Crew Companion is born in October of 2007 as the second generation of the original eTripTrader application. 18 years later Crew Companion serves over ten thousand United Airlines pilots.
eTripTrader created by former United Pilot.
Tom Lajoie founded eTripTrader, Inc. in 2002, to provide ‘a better quality of life’ for his fellow United Airlines pilots. The product was built by Tom and his oldest son Chris with an effort to convert a long and painful process of trip trading down to a matter of seconds.
