Well,I waited 90 minutes then gave up and filed missing bag report. There were no more bags on the carousel but the customer service told me they are still unloading some bags from that flight.
I was polite but.told them there is no way I will wait over and hour and a half for a bag and they just have to ship it to me if found.
I was in the air for 25 hours with 3 different airlines,who knows what went wrong where. But I fly enough now to know that a wait of over 90 minutes is absolutely not acceptable.
