@Mamacita I haven't had an issue to date but am just concerned as I will have to book it whilst on hols in Italy, and I am not sure the website will behave with or without vpn. Am going to try a dummy run the day before to see what happens with it.
@Tinkerbell cat unfortunately I won't be able to call BA as I will be on hols in Italy at the time I need to book the seats -355 days out. Just unfortunate timing this year

as we are tied to trying to get specific dates next year to holiday in September.
Well done on getting your seats to LA. In previous years I've managed to get to Mauritius, Sydney and Singapore, so really hoping I can bag the KL seats as we have plans for Asia next year!
