A couple of questions re earning triple Avios:
- Does the booking have to be via the Website or will a booking via the GGL line work?
- Does the currency of the booking matter? e.g. if I book a flight originating in ZRH the website will normally price in CHF - will that credit OK?
- (more of a general BA question I guess) if the answer to the above is that GGL line bookings works, given the currency charges on the card am I best placed to ring the GGL line and ask them to price the journey in GBP? Or does that risk changing point of sale and thus price?
