Got to go with David_itl's suggestion. How could you be in MAN and resist a flight on a bmi 332!! And, now that they have an earlier departure time, you can have a fairly leisurely jaunt through ORD and return via IAD (or VV, depending on your preferences). Work it out right and you'll get to fly on types you may not have flown before. And don't forget the bmi airmiles. STAR Alliance airlines are much more generous and besides which, US Airways points mightn't be too valuable in the medium term . . .
