In planning some international trips my biggest fear is what the fuel surcharges will be on foreign airline segments, especially when booked via Aeroplan or British Air. How do we know in advance what these charges will be and is there a way to avoid them other than only booking through USA airline programs or flying USA metal on bookings through foreign programs. Also, are there certain airports other than Heathrow to avoid because of high airport fees? Some of these fuel surcharges I've seen are absolute deal-breakers on award flights. Lastly, is there any chance these fuel surcharges could come to USA airlines, effectively killing off frequent flyer programs?
