Narrative: We were released to ferry [Aircraft X] to ZZZ. The flight plan fuel was 4;000 lbs. We blocked out with 4;100 lbs. on board. The destination forecast did not require an alternate. There was no indication from ATC prior to departure that traffic flow into ZZZ was restricted. Once airborne and abeam VOR;  Center cleared us direct to ZZZZZ intersection and issued holding instructions with an initial EFC of XA45Z due to thunderstorms at ZZZ. We sent an AFIS message to Dispatch informing them of our holding situation. We estimated how long we would be able to hold based on fuel on board. Our EFC was subsequently changed to XB05Z. XB05Z was approaching and we were evaluating weather at potential diversion airports. We queried Center if  ZZZ1 was accepting arrivals.  Center indicated ZZZ1 was indeed accepting arrivals. At XB05Z our EFC was extended to XB30Z. ZZZ weather not improving. We told Center we needed to divert to ZZZ1 and we were cleared out of holding on a 180 degree heading for vectors to ZZZ1.  Center came right back to saying ZZZ1 was going into holding. We told Center we were diverting to ZZZ2 and they cleared us to ZZZZZ1 intersection and then on a heading approximating a right downwind for RWY28R at ZZZ2. At ZZZZZ1 we were handed off to ZZZ2 App. Thinking other planes could be diverting to ZZZ2; We asked what our sequence was for landing. ZZZ2 App said '5 or 6'.  We declared Min Fuel with approach to minimize delay getting to the runway. We blocked in with 840 lbs. fuel on board. Summer weather in Florida usually equates to thunderstorm activity. Our planned trip to ZZZ was only 27 minutes. 1175 lbs. of 'extra fuel' was included in the flight plan. On the surface; a 4;000 lbs. fuel load seems completely adequate for 162nm; 27 minute flight with no alternate required. Requesting additional fuel for the unexpected would have been an easy thing to do but didn't seem necessary at the time. Established in holding we expected the storm to move east and clear out of ZZZ. We could have initiated the diversion as soon as the EFC was extended the first time allowing us to have a more optimistic fuel situation. We were not expecting ZZZ1 to shut down so quickly forcing us to change diversion plans again.




Synopsis: A Citation Sovereign Captain reported diverting and landing with minimum fuel remaining due to unanticipated weather delays.
