We are a family of 7 going on a holiday to Florida. The flight is with British Airways and was booked by my brother, and he paid for all our flights with his credit card.
The British Airways Login Page shows his wife's name and email as contact details even though he paid for everything through his credit card.
They have separated now, hence his wife has threatened to replace his name with someone else's. Can she change or cancel his flight in any way i.e can she tamper with the tickets in any way?
