Higher altitude, not lower. The higher you go, the less you burn. Of
course, you have to be able to get there in the first place and not burn
so much fuel doing so that it offsets any gain from cruising that high.
The decreased burn is so dramatic, UA 757's between SFO and SNA (323
nautical miles) routinely operate at FL410 (41,000 feet).
