They usually fly economy but after their last flight are now thinking of starting to fly Premium Economy or Business, and they are also willing to use LHR as a hub and take cheapie flight to Milan.

Based on the above, is there any benefit to choosing UA over AA?

The only one I can think is that UA waives the spend requirement for those with an overseas address (they have both). Any other differences we should factor in? I know questions like this are boring, but your expertise would be appreciated.
