The exception to that is if someone is using a VD to the same airplane type. If a senior MSP MD88 FO elects to take a VD to ATL MD88 FO, he'll be able to use his seniority, not the seniority of the junior pilot who would be displace.

I was able to take advantage of this first hand. When there were displacements in ATL, I was able to take a VD from the ATL7ER to LAX7ER even though the junior ATL 7ER pilots were not senior enough to hold LAX. To be honest, I wasn't aware of the exception at the time and was surprised when I was awarded the position. Another testimony to "Bid what you want, want what you bid."
