If I have an existing booking for travel after 28 April, will I collect Avios and Tier Points based on the new rules?
No. All existing bookings will be honoured under the current rules; the new rules will only be applied to new bookings made on or after 28 April 2015.
That seems to imply that all existing bookings earn as now. My understanding was that this included ALL bookings (i.e. IB, AA, AB).
