A flight crew arrived at their destination with minimum fuel but failed to declare a fuel emergency....

Narrative:

While planning this flight I looked to see what flights were departing towards ZZZ. I saw another carrier's flight that was going to this same destination. I took their route and built a route to avoid weather. The captain called and stated that ATC was going to reroute the flight a little south out over hct; then direct onl. I got a call about 10 minutes later saying that they got 'as filed'. Then when the flight got off the gate they sent an ACARS message to state that there was a long line for departure. I asked them to keep me updated as to their fob. At one point I asked how hard it would be to return to the gate and I was told 30 minutes wait. Fourteen minutes later they were airborne with 8.6. Den ATC had both arrivals and departures crossing through the same airspace. Over gld I asked what their fob was and got 5.6. I tried to run numbers and got 'unusable route' from the dispatch monitor. A few minutes later I got an ACARS that said that ATC wouldn't let them climb. When they got to their destination the captain called to add that ATC kept vectoring them even though they had declared minimum; fuel eating into their reserve. Flight landed with 1.9 and arrived at the gate with 1.8.the issues with ATC; I don't have objections to; but the dispatch monitor needs to have the bugs worked out so any request for numbers will yield results.

Original NASA ASRS Text

Title: A flight crew arrived at their destination with minimum fuel but failed to declare a fuel emergency. Inclement weather and associated ATC delays enroute contributed to a landing with less than FAR reserve fuel.
