7 new airframes and where are the commands coming from??? The Sustaining Fleet!!
The last 400 commands went to 400FOs, none of the 300 Capts wanted to move across. But even if they do that still only equals 30+ extra commands. Either way it's happy days for any FO that has been in for about 2 years and has the requirements.
DECs are possible based on the current EBAs, however you would still have a seniority less then anyone employed before you, so as all the FOs you jumped come up for command they will straight away be more senior to you in bidding/ holidays etc.
