Rumor at RAH is that CHQ and Shuttle will likely be merged. 170s were put on CHQ certificate initially but APA fined CHQ something like 6 million for this and the mulitple certificate kabuki dance was born. Now that the AA/Continental 50 seat scope has been gutted, the business justification for these multiple certificates are gone, along with the horrendous expense of running multiple SOCs, maintenance, training programs, etc.
