Narrative:

After arriving; we had a note from scheduling advising us of a reroute. We found out we'd be flying a plane instead deadheading. The aircraft had a gear issue and needed to be flown under an MEL with the gear extended. I called dispatch to check on the fuel load; because it seemed low for the flight. The dispatcher went over the chart while I was on the phone and assured me that the fuel load was correct for the intended flight with the gear extended. I was concerned and bumped the fuel about 1000 lbs. After climb while in cruise; the first officer and I could see that the fuel was not going to be adequate to arrive at our destination with the proper reserves. We made a decision to divert and coordinated with dispatch. The dispatcher agreed with the divert plan; and he sent an amended release plan to show the new destination plan. We arrived without incident; took on more fuel; and continued as normal. I would like to have a chart available to use as a backup for this type of operation. Crews should follow along with a chart for this type of operation.

Title: A B737-700 Crew reported that prior to a flight the landing gear MEL'ed down; they questioned the dispatch fuel load and in fact added an additional 1;000 lbs. At cruise the crew determined that insufficient fuel was on board to cover destination reserves and so diverted enroute for fuel.
