British Airways today announced the acquisition of Paris-based airline L’Avion, to work in tandem with its own fledgling carrier OpenSkies on routes from New York to Paris Orly.

The addition of L’Avion will support OpenSkies’ mission of broadening British Airways’ operating landscape under provisions of the recently adopted Open Skies Agreement between the US and the European Union. Beyond the greater access to a relative handful of seats, though, potential benefit to travelers is difficult to predict.

According to a press release from OpenSkies, “Once the two airlines are integrated, customers can expect to experience benefits that will further improve the Paris–New York offering, including an increased schedule and BA Executive Club privileges.”

What might the integration of the two airlines entail? L’Avion’s two all-Business Class 757s are outfitted with 90 (low-performing) seats, while OpenSkies’ lone aircraft is a three-cabin configuration with a nod to high end. It seems unlikely that the merged operation will retain two products so diverse.

Another clash between the new siblings is that in their existing code-share, L’Avion’s Business Class is considered by BA to be equivalent to OpenSkies Premium Economy. Look for that wrinkle to be ironed out in the days ahead.

And what to do about that name? L’OpenSkies, anyone?
