If you're talking about matching it "for you" - i.e. if you call them and ask for an exception, I doubt it. You could call the OPSC and ask. If you do, certainly report back here what they told you.

If on the other hand you're asking if CO might match this promotion for its own transatlantic service, its marginally possible, but I strongly doubt it for reasons ranging from prior CO strategy to dissimilarity of markets served to more reasons. Don't hold your breath for this latter option is my opinion.
