Thanks, anabolism and Gardyloo, for the excellent suggestion re: booking with AS. My personal experience with AS has been can-do, customer-centered service, which could be very useful when dealing with ticketing and changes (expected and unexpected). I'm hoping to ticket my DONE4 ex-BUD pretty soon for travel mid-Spring and will share what I learn about fuel surcharges. It will also be interesting to see how willing they are to construct a complex itinerary that may only include a single AS flight but also includes many requests for specific codeshares on other carriers.
