I should add that ALL posts referenced by irishguy28 are for instances where the OPs bought the tickets DIRECTLY with the airline, not through a TA.
They're also for other airlines not EY.
I should also add that Etihad's terms and conditions are in relation to their websites (i.e.
www.etihadairways.com,
www.etihadholidays.com,
www.etihadguest.com and
www.etihadcrystalcargo.com). The section which is referenced clearly indicates the use of credit cards on Etihad's websites.
What an utter waste of time and effort irishguy28.
