Hi.
Pushing the limits is usually the specialty of US airlines, majors including.
Good examples are Continental and now Northwest flying 757s across the Atlantic (NWA is still going through mods in other to make them capable of switching from a lousy "domestic" version to a slightly nicer "international" version).
then you have the 737 NGs flying coast-to-coast in the US or better west coast to Hawaii which again is a pleasant trip (757 as well) considering you have a choice between that and flying with Hawaiian Airlines (same routes) which is exclusively 767s.
Sky is the limit, right
