BizElite and BusinessFirst are both terrific products and are well ahead of AA, UA, and US in the amenities and
accolades for their efforts.
I personally prefer BusinessFirst because it remains the
original and best attempt at fusing First Class service
with Business Class fares. However, I have flown Biz
Elite twice to Europe from JFK and thought that it was
excellent in every way. The seats did provide just a
tad more legroom but overall, I think both products
get an A for their quality and consistency.
