i have tryed flysmart within europe. 2 of my friends and me traveled together. we flew muc-ist over a weekend. i did not seem to be too hard to get 3 seats but i had to be flexible with the dept. and arrival date. so we left fri and returned on mon. after all everything worked fine. i would say it is not hard if you are flexible on the dates. a lh rep. told me to call first thing in the morning to book the filght 14 days before departure since "seats are limited".
