Flying out of T5 tomorrow AM. We are already checked in and have our BP after our connection from GLA today

There are 5 of us flying J, 4 adults and an infant. I am GCH, my wife is a SCH and my in laws have no status.

We need to drop our bags, as we needed them this evening, so they weren’t checked through.

I don’t normally get to use the First Wing, as I normally connect on the same day from GLA.

Will we all be able to use the First Wing for bag drop? I then presume my In Laws will have to go and use the normally priority security.

Re bag drop, is it the same queue for everyone, or is there a quicker bag drop queue? Thanks
