first, I wasn't making a fuss about anything. I was simply trying to understand what aircraft and cabins AA would NOT offer the stuff it touted in the press release.
Second, DL is the only one of the big 3 that has AVOD at every seat on every longhaul int'l aircraft. UA also has 767s that it has not retrofitted. I don't know their plans to retain those aircraft but they have indicated that they recognize the need to slow capital spending and to retain some of the mainline capacity they have intended to park.
As for business class, UA says they are at 100% lie flat business class on their entire int'l fleet; DL is at 100% on its widebodies, all of which have direct aisle access. AA IIRC will follow the direct aisle approach to business class, IIRC, but they are a lot further behind in retrofits.
There are also significant differences in terms of soft amenities including free alcohol policies between the 3.
so, no, all 3 US airlines DO NOT HAVE the same level of onboard service - either soft or hard product.
and as I have noted before, DL has the advantage of pulling off the first completed merger and has also taken the approach of offering a high quality product.... you can still get power and WiFi on DL aircraft but you also have an AVOD system if you want it.
AA might have decided they aren't going to go with any AVOD on domestic aircraft - the industry is far from being on the same page. US and NW both took fairly stripped down approaches to in-flight entertainment. DL's acquisition resulted in NW's policy being eliminated; since US took over AA, AA's product approach reflects a different approach and AA people on here have said so.
