You shouldn't have trouble if tickets are on separate airlines. Just make sure you leave enough time between the New York and Asia flights that you have a back-up plan in the event a flight is late. etc. As you say, leaving a 90 min. connection between airlines from a trans-Atlantic onto a trans-Pacific is foolish--- let alone the fact that your body won't like it.

To be the safest, choose different airlines _and_ FF programs, i.e. flying one RT on BA and one RT on AA but pooling both into the same account may raise trouble-- not likely, but possibly.

Very separate aside: Northwest has about US$250RT fares after tax New York to London. These must originate in the US, and you can reserve through nwa.com or travelocity. Just note that the fares are only valid if you connect to/from DTW--LGW flights on NW, meaning you'd have to change airports to go to Heathrow.

Good luck.
