The store will be open regular business hours (Tuesday-Friday 11-7, Saturday 12-5). I would be happy to stay open later/come in on Sunday or Monday if anybody wants me to--please call the store 708-484-7899 to make arrangements. My cell # is 773-213-9494, if I'm not at the store. I live nearby and it's not a big deal to come over to Fly Right to let you shop at your convenience.
I'll be closed on Christmas Day, December 25th. I'll be open the 26th and 27th--then I'm going to close for a few days. I'll post exact dates once they're confirmed.
Here's wishing you all a Happy Christmakwanzikkah!
