Ladies and Gents, I'd like to know if anyone can shine a light on something for me. I'm planning a trip to LHR from YUL, Jan 14, return Jan 19. I looked up the flights on expertflyer, and both the 864 outbound and the 865 inbound are "0" across the board, yet the flights are pretty wide open, and the prices are low, and available in every class. Any ideas what the "0" 's indicate?
