Narrative:

We were under control of ATC (I think ZKC) and they gave us a rerte for WX and en route spacing into den. The rerte sent us way south to alamosa and our FMS and our own calculations determined that with the rerte we did not have enough fuel to be legal to fly to den and cos (alternate). We asked for a better route and they told us unable. ATC then asked if we were an emergency aircraft. We stated no. They said we could not proceed to den on a more direct routing unless we declared a fuel emergency. Captain stated that we were dispatched legally with enough fuel to land at den and also have alternate fuel for cos. ATC gave us direct den and declared us an emergency aircraft. The rerte would have brought us some 100-150 mi off our original course which most aircraft would not be able to comply with without stopping short of their original destination.

Title: WHEN THE FLC OF A B737-300 ADVISED ARTCC RADAR CTLR THAT THEY DID NOT HAVE SUFFICIENT FUEL TO TAKE DELAYED ROUTING PROPOSED DUE TO WX AND TFC, CTLR DECLARED AN EMER FOR CREW IN ORDER TO GET DIRECT ROUTING.

Narrative: WE WERE UNDER CTL OF ATC (I THINK ZKC) AND THEY GAVE US A RERTE FOR WX AND ENRTE SPACING INTO DEN. THE RERTE SENT US WAY S TO ALAMOSA AND OUR FMS AND OUR OWN CALCULATIONS DETERMINED THAT WITH THE RERTE WE DID NOT HAVE ENOUGH FUEL TO BE LEGAL TO FLY TO DEN AND COS (ALTERNATE). WE ASKED FOR A BETTER RTE AND THEY TOLD US UNABLE. ATC THEN ASKED IF WE WERE AN EMER ACFT. WE STATED NO. THEY SAID WE COULD NOT PROCEED TO DEN ON A MORE DIRECT ROUTING UNLESS WE DECLARED A FUEL EMER. CAPT STATED THAT WE WERE DISPATCHED LEGALLY WITH ENOUGH FUEL TO LAND AT DEN AND ALSO HAVE ALTERNATE FUEL FOR COS. ATC GAVE US DIRECT DEN AND DECLARED US AN EMER ACFT. THE RERTE WOULD HAVE BROUGHT US SOME 100-150 MI OFF OUR ORIGINAL COURSE WHICH MOST ACFT WOULD NOT BE ABLE TO COMPLY WITH WITHOUT STOPPING SHORT OF THEIR ORIGINAL DEST.
