Hi FT-ers,

My parents and I are flying J to JFK on 13 August. We would like to take a different flight from our current booking and BA.com is showing several available--mostly 777s. What is the current refit situation with these? One is a 4-class, another a 3-class (comment: been a long time since I saw a 3-class on the JFK route). Is AVOD now across the LHR-based fleet?

Many thanks!
