Does anyone know of another airline that has four classes of service?

I recently flew economy dleuxe on EVA air (http://www.evaair.com.tw/english/eindex.htm) which has four classes on their 747 flights (the other three classes are super first, super business, and economy).

On my particular plane, the 747-Combi, the business (16) and first class (8) seats are on the second level. The main level has seats for 86 deluxe and 162 econ seats. The rear cabin of the main level is converted for cargo.

The deluxe class turns out to be a bargain and has services that rival most first-class domestic US airlines. The seat size are the same or slightly bigger than that of UA business class (in a 3-class plane) with 38" between rows. Other amenities include seat-back videos and excellent food served on bone china (on a flight less than 2 hours!).

The cost of economy deluxe is only slightly more than economy.

As anyone who has flown to Asia can attest, flying coach sucks! I wish domestic US airlines can also outfit their 747s the same as EVA. But knowing the way they like to cut costs, this is extremely unlikely.
