DOH for the latest junior upgrade on the ERJ May of 2016. Junior for the CRJ August of 2018. Do you want to have some time in the aircraft you are going to be upgrading in? Are you hoping for a quick upgrade?
And everyone that upgrades as soon as they can on the ERJ goes to LGA. Next junior award to another domicile, which was ORD, is March of 2015.
