On my recent flight (777) I was looking at the inflight phone which is built into the handset. For the duration of the flight the display read "Phone service unavailable"
AVOD was unavailable?
Not on BA, but I've used these on QF. Our A380 MEL flight was delayed out of LAX and diverted to SYD due to crew hour limits. Phoned SWMBO to get her to act out her PA role. ^
