Saw a Lufthansa 747-400 come into Oakland today. Only stayed a little while and then completed it's flight to SFO. I suspected it was a fuel diversion due to heavy winds. Anyone else know anything? Always fun to see at OAK.

Quoting QANTAS747-438 (Reply 4): I understand diverting due to low fuel, but a 747 diverting to OAK from SFO? Really? It's 8-15 miles apart. Wouldn't a long haul 747 arrival get some sort of priority for landing at SFO?
Just because a 744 is easily capable of making the FRA-SFO easily, doesn't mean the 744 is filled to max capacity in fuel. They are only required to carry enough for 1-hour margin in fuel. With fuel prices the way they are, the amount of fuel to add to the aircraft is probably down to the gallon.
Although SFO and OAK are only a few miles apart, the weather between the two could as different as night and day. Sometimes during this time of year, the on-shore flow can cause some traffic problems at SFO. It's not all that uncommon for SFO to send diversions to OAK and SJC.

I know all that. Here at WN, for example, if we have flights going to MDW they divert to STL or OMA, but those are 300 miles away from MDW. I just haven't heard of a jumbo diverting so close to the actual airport!
My posts/replies are strictly my opinion and not that of any company, organization, or Southwest Airlines.
There is no landing priority unless min fuel or a fuel emergency is declared and that opens a hole can-of-worms. It doesn't matter how close OAK is, the fact is they were not landing at SFO till their spot came up. By the time LH is scheduled to arrive, we (SkyWest) were still getting 9-10am arrivals that had take 2 hour delays. Actually despite what Wedge say's above, weather at OAK could even be exactly the same as SFO and planes will still divert there for the fact that OAK is not nearly as "busy" as SFO.
The example with WN you give is much different. Flights you exampled will divert because of weather related issue's like area thunderstorms, blizzards, etc. Weather that we don't get on the Left Coast commonly. SFO is just a unique position as a very busy airport placed in a wind driven fog machine. "and no offense to OMA or even STL, but they rarely have 20 planes in holding at once".
Guessing (pure speculation) that LH dispatch and crew looked more at ceiling levels and whether there was rain (not this time of year) in the area while flight planning. And it's not like we were getting +50 mph winds.
They very well could have burned more fuel en-route then planned.

I suspect its nothing to do with the fact that SFO is marginally farther away than OAK, but more to do with the holding delays and congestion getting in to SFO, whereas they almost certainly were able to drop straight into OAK with no hold.
Also, flight times from Europe to the west coast have been much longer than usual, mainly due to headwinds which are proving difficult to predict. That quite possibly added a few minutes flying time. Throw in a holding delay on arrival and the crew probably found that their contingency / holding fuel was not sufficient to avoid a precautionary diversion.

This happens frequently...At FLL, I remember seeing an AZ 777, Polar Air Cargo DC-10, AA 777 and other assorted diversions headed for MIA. These two are a little further apart than SFO/OAK -- but weather can be completely different just a handful of miles away.

I've landed in heavies diverting into RTM from AMS, OAK from SFO and AFW from DFW just within the past few years. There are plenty of reasons beside weather why an airport less than 20 miles from the intended destination is a diversion point.
