Tor Air's correct 3-letter/ICAO code is "OAI"...so it would be my guessing that someone at Newmarket has made a small error in entering the flight numbers in their system...ending up with flights loaded as "OA"
This year, the Newmarket flights were operated under OAI flight numbers of Tor Air with an aircraft leased from Small Planet - so it would appear that they are planning the same for 2012?
