I was just checking to see if I could switch from the BA85 to the BA87 on June 16th. I was surprised that I got so many options to travel to YVR that day. So, for the hell of it, I tried CPT, BKK, EZE, JNB, SIN and even SYD. They were all wide open for redemption in CW. Is that normal? Are last minute bookings always this easy? If that's true I am never bothering with the book-early stress again.
