Just to add, OO did the deal with the understanding that it would be the SOLE Continental express carrier after the deal.
Little did we know, Continental and UA were already in talks and by the time the 2010 deal was done, Continental was a thing of the past.... and so was OO being the sole operator.

Also, is XJT is mad at anyone, it should be Mesa.
In 2016 Mesa came to IAH and undercut everyone.
That took XJT from 200 to 100 jets, 50% loss.
That also to OO from 100+ lines to 20 lines, an 80% loss,

That really started the XJT decline in my opinion.
