Delta Airlines gives this stuff out both in amenity kits when your luggage is lost and in their lounges (the few that have showers) along with a super-cheap 2-blade disposable. Once when flying home from India through JFK I stopped in the Sky Club (then Crown Room and/or Business Elite lounge) for a shower and made the mistake of shaving with the combo (back pre DE/wet-shaving). It was one of the worst shaves in my life... probably second only to my last barber shop shave.
