Looks like San Jose’s first ever scheduled commercial (I think) 747-400 will be on British Airways next year!
According to the available information on britishairways.com’s booking system:
The 747-400 will operate London Heathrow to San Jose (SJC) from Sunday, March 29, 2020 to October 24, 2020
(Oliver Richter on JetPhotos)
The flight will depart LHR at 2:25 p.m. and arrive in SJC at 5:45 p.m.
The flight will depart SJC at 8:10 p.m. and arrive in LHR at 2:30 the next day.
@BigBert10 and other SJC people:
Note this is still subject to change as this is about 4 months away.
Congrats to SJC for securing this flight if true!
