You have three options if British Airlines abruptly Cancel your flight:

1. Take British Airways' next flight when it becomes available.

2. Opt for a different British Airways flight that works for you.

3. Request a complete fare refund.

You can either phone British Airways and ask them to modify your flight reservation, ask your travel agent to change your ticket if you bought it from them, or change your ticket online using Manage My Booking.
