FYI. Shifting by a couple of days could significantly increase the cost for international applicants because international flight prices often increase steeply in the two weeks leading up-to the the flight date.
Not only tickets matter for international applicants, I believe, there are a lot of applicants who have a visa-stuff going on... And this is more troublesome than expensive tickets.
US Embassies change from country to country so don't read this as gospel, but if you don't have your visa 15 days before the interviews you're probably too late now :(
Well,I think the tickets and visa stuff should be figured out by the applicants as soon as they submit their app assuming that you should get a call,cancellations might cost cheaper than booking at the last minute
I'm from France and personally don't mind paying more, as long as I get there and get a chance of serious funding... Even though my finances are extremely limited
