As a follow up I was just reading the
ABD website and came across the following language regarding cancellation of trip by ABD and refunds on airfare (not purchased through ABD). This makes it seem like ABD will reimburse airline cancellation charges, if they cancel the trip. That is all I am concerned about, as I have NO intention of cancelling!!
"If we cancel your trip prior to its commencement because there are too few Guests: (i) We will attempt to rebook you on another departure of the same itinerary, subject to availability, and we will bear any reasonable airline rebooking charges; however, if we are unable to rebook you, we will issue a full refund of your land package price and plan (unless you have filed a claim); and (ii) if you booked airfare through us, we will issue a full refund of your airfare; and (iii) if you did not book airfare through us, we will reimburse you for your reasonable out-of-pocket (subject to proof) airline cancellation charges or, in the case of bookings using frequent flier miles, a reasonable cancellation service fee, provided you have exercised best efforts to mitigate such charges/fees; and (iv) the aforesaid payments and/or rebooking by us shall constitute a full settlement."
