Well OO has 113 CRJ200’s for UA plus a few generic paint “floaters”. With UA saying ruffly 100 50 seat aircraft i foresee the majority of them being the 145xr. I wouldn't plan on OO flying more then 40-50 for UA when all is said and done. And thats on the optimistic side.. But OO has used 700’s lurking in TUS waiting for a home.. so maybe we dive into the 550 world. But doubtful… As they can lease them to G7 and go after more 175’s with the excess staffing.. but attrition is going to go through the roof soon.. but as UA puts there new aircraft online the 175 pairings are going to suffer as the 737/A320’s take the longer E175 flying.. Just my observation.. cant wait for the next OO earnings call. See how they answer the questions on this!!!
