In view of recent PRIVATE EQUITY involvements with WestJet... I think one has to keep watch if this was a first strike in preparation for other dominoes.
Indeed. Onex has enough capital to also buy Transat AT.
Despite flying different equipment (and having totally different culture...) we can see the complementary reach of each airline: WestJet being strong in the west, average in TO and extremely poor in French speaking markets (Transat being the other way around).
In such a scenario (and if they can somehow keep both airlines/pilot groups separated
), I can see Transat's A321LRs usefulness for some WestJet's longer thin routes. And WestJet (+Encore) could efficiently feed some Transat's transatlantic routes.
The older crowd will remember when Onex (then financed by AA?) made an hostile Canadian & Air Canada take over bid in 1999. Their plan was then to move AC from Star Alliance to One World...
Above scenario is obviously highly hypothetical. It could also be that Onex has no interests in buying AT whatsoever.
