Hello, I am still at loss about this. I go to Avianca website, select even United States / English website. Put a date (beginning of June), I see all options XS - L. Absolutely no mention of resident vs non-resident. I look at Flight details, flight restrictions, anything I can look at and see no mention that I need to book L. How would someone be supposed to just "know" they have to book L? There's no mention of any fee if I book a lower package (I just need S). Is it possible that for some reason there is no difference at the moment? Or is it some scam by Avianca to get people to pay the fine?
