Weather
Held on STAR due to weather going into ZZZ. Once vectored off and assigned different STAR we were notified that there were micro burst alerts at ZZZ and it would be at least 40 minutes for landing. Not having the fuel to continue to hold we opted to divert to BFF where we would land with 5;500 LBS of fuel. Approximately 60 miles out from the field we were informed that we would be holding due to volume of aircraft diverting to BFF. We informed the Controller of our situation and ultimately declared minimum fuel when the time came. The issue we faced was that at least 2 out of the 5 aircraft going into BFF were also in a negative fuel state and aircraft were not canceling IFR quickly enough at the uncontrolled field to allow a constant flow of landings. We were ultimately vectored onto approach and landed uneventfully with 3;400-3600 LBS.
First Officer reported aircraft diverted to alternate airport and landed with less than minimum fuel onboard.
