Oops. Bit of a problem now. I booked my flight on 8th July to ensure it was under the old rules not the new ones, but just phoned Etihad to try to arrange an upgrade with points, to be told that the new rules came in for bookings from 8th July onwards. I've checked the various communications and Etihad's website, and they are ambiguous. For example cut and paste below from the FAQ page - note the use of "before" and "after" 8 July without clearly specifying what the cutoff date was. In other places different forms of words are used, but this isn't the only place where "after" is used.
"If I have booked an Etihad Airways flight before 8 July 2015, but I will be travelling after 8 July 2015, how many Miles will I earn?
The number of Etihad Guest Miles awarded will be determined by the date you bought the ticket, not when you are travelling. So, only tickets issued after 8 July 2015 will be affected by changes to earning rates.
For tickets issued prior to 8 July 2015, the current earning rates will apply, even if you are travelling after this date."
That would seem to be pretty clear cut. After is "After".
I'm sure the ACCC would agree. How about calling the travel ombudsman for their opinion?
