Where might one look for a current, apples-to-apples fleet comparison between the legacy passenger airlines? A mid-30s military friend who is willing to live in any domicile is trying to decide whom to prioritize. He wants to fly international and it seems like Chicago with United would be pretty ideal. They appear to have almost 100 777s including orders (APC profile, but I don't know if it's accurate), and FOs with 2 years can hold it? 787 options in HOU and SFO look good too. He has zero interest in cargo.
