One of my most frequent and best uses of American AAdvantage miles over the past 7 years has been booking first class awards on Etihad. I’ve used them to fly to the Maldives four times, to India, to the Gulf region and from the Mideast to Australia to name just a few.
And they offer an excellent hard product in first class – on their Airbus A380 the ‘First Apartment’ with an on board shower.
