So, I booked AA222 for tonight (LGA-ORD) to be in Chicago for Shabbos in First using Avios. This afternoon, I got an email that it was canceled.
After a ton of HUCAs, I was able to get myself an itinerary in economy 5:45 am LGA-CMH and 12:06 pm CMH-ORD.
1) is there any chance I could still get rebooked on a nonstop at airport?
2) is it risky checking bags on this flight if I need stuff for Shabbos?
2a) what would AA reimburse me as a result of delayed baggage?
3) any type of comp I can request (once I arrive in ORD in one piece be"H)
Thanks for any advice.
