 In January 1949, the CAB concluded its investigation and announced plans to roll out significantly harsher regulations along with a series of punitive measures aimed at irregular air carriers, all of which were presumed guilty of some infraction during the preceding years.The new mandate would suspend each large irregular passenger carrier's license to operate pending a thorough review, and restrict the non-skeds' flight limit even further to varied weekly flights and four round trips per month between any two destinations.Additionally, the CAB introduced statutes prohibiting cost-sharing between non-skeds and requiring that each have their own ticketing agencies, effectively banning the elusive combine schemes.
