OP probably used miles, that's what I do.
I managed to use AA miles to fly Eithad's first class apartment from Abu Dhabi to JFK.

The sofa on the left side of that photo converts into a bed.
In the last six years I've earned and redeemed about 2.5 million frequent flyer points, so I've managed to fly first or business class around the world several times over. Beds in flight, top-shelf champagne, 21 year old Japanese whiskey, caviar, showers in the sky, complimentary limos to and from the airport, free massages at the airport. When I flew first class on Lufthansa out of Frankfurt they drove me across the tarmac to my plane in a Porsche.
Last year I flew to New Zealand and back via Asia in first class. Outbound I flew Cathay Pacific in first via Hong Kong, then returned using Air New Zealand business class, Singapore Airlines first class and All Nippon first class via Sydney, Singapore and Tokyo. All told about 180k miles and a couple hundred bucks in taxes and fees.
