If anybody wants to confirm 248 you can call me 514 and we can depend 1980 on each other for a sure ride?
What? I don't know your secret code?
I could be in the Concord area Friday morning. I did a fare estimate from the Concord Hilton hotel to Oakland Airport and the estimate is $42-$55 (1.0x).
I have seen frequent surges in the Concord area in the morning because sometimes the rider demand is higher than the driver supply because ride demand is pretty much very low at night compared to San Francisco, Oakland, and Berkeley. Be aware that if you request Uber on 9/25 (Friday), there may be a fare surge around 4:20 am for business travelers who need to get to SFO or OAK for morning flights.
If you miss the 4:12 am Concord to SFO train and you miss the transfer at MacArthur station at 4:38 am, you may not be able to check-in your flight on time.
