I'm also curious who normally now uses the old WN checkpoint, when it is open, and if it has TSAPre? I know the plan may be that if inbound pax arrive on international flights once they clear from the FIS it will be more seamless to enter security to connect to a B6 domestic flight at E.

I did hear that El Al uses E1B and that they may have their own security checkpoint for that gate. I'm not sure who uses E1A?

I always liked the old WN checkpoint it was usually not crowded and relatively quick to go through.

I don't really like the large C checkpoint especially if I am just taking a quick day trip say to DCA. I prefer more the AA shuttle checkpoint at gates B15-B19; very quick! The e1 gate checkpoint may be good for these short trips.

It would be nice for the large C checkpoint if they got Clear! Clear+TSAPre is great you only scan your fingerprint you never even have to bring or take out your id and then you just also scan your mobile boarding pass.

I'm also curious how B6 is choosing what flights to put at the shiny new C10, C9, and C8 gates, Mint, Random flights?
