I've been trying to book some seats from Istanbul to Vancouver, which LifeMiles shows is available when I search for seats by month, but when I click on one of the dates that is shown as available in both LifeMiles and United all I get is "Not available". I've used both smart search and Turkish airlines only search and both of them show Turkish availability at first but show no flights available at all when I click on any of those dates. (Cant post any pics because I need to have 5 posts to upload them)
