According to Airlineroute, Oakland is showing again in the GDS booking systems from 1st April 2019. Because ba.com only lets you book 355 days in advance, the first service will not be available until midnight tonight.
Loads have been very weak according to first hand reports and this may be a good option if you want multiple Avios seats to the US for next Easter.
To maximise your miles when paying, your best bet is the British Airways American Express Premium Plus card which earns double Avios (3 per £1) when you book at ba.com or via BA Holidays. You do not get double Avios if you book with the free British Airways American Express card. Another option is American Express Preferred Rewards Gold which offers double points – 2 per £1 – when you book flight tickets directly with an airline.
