Hello again. We are planning a June 2013 trip SEA - GOT, and would like to stopover in either AMS or Paris for about 3 weeks on one of the legs. These flights normally connect in one of these 2 places. In the past, when I have done this before, it was on award travel, and in the times when you had to call the awards office & make the arrangements (and the stopover was at no extra cost).
So I have 2 questions. Is is still an available possibility (at no cost) on most airlines? We probably would be going Delta/KLM or Air France. And if it is still possible, is there any online way to specify this stopover period, in order to check available flights & costs?
I have looked at the multicity possibility online but it prices the trip significantly higher than a straight round trip. Thanks!
