Reminds me of an experience I once had on UA down the back.
Checked my bag in at ORD only to be told 10 minutes later, sorry you ain't going nowhere due to snow storms. Come back tomorrow. Can I get my bag back? No.
Next day "can I fly today?" Yes. Check in again then on to aircraft pushed back into holding pen for 2.5 hours. What joy.
Finally arrived in BOS to a sea of checked bags that I had to pick over until I found mine.
