Yeah, that's the one I was actually concerned about canceling and then causing me to misconnect to my EWR-TLV flight. (They've already canceled the first two IAD-EWR flights tomorrow morning.) I didn't realize until after I posted there's another (evening) EWR-TLV they'd probably stick me on. Whatever happens, I'm hopeful they rebook me in full Y and let me apply a GPU.

I was able to switch from a Q200 IAD-EWR to a 757-200 that's currently sitting at IAD and much more likely to make it into EWR than a little turboprop. So, I'll probably be OK. Still, if anything happens, I'll definitely let you know!
