I fly US-South East Asia a couple times a year. Economy fares are around $1k(or $500-800 the last few months). Business class fares can be had for about $4-5k. Premium economy for around $1,500-2,000. My problem with premium economy is that for 50%-100% more than the economy fare, you're not getting much. Slightly(1-2") larger seat and pitch. Slightly better food. Earlier boarding. I wish they would have something in the $2,000-2,500 price point with those recliners that you find in domestic first class. I'd definitely pay that much for it.
