Eos and Maxjet have kicked the proverbial bucket, but the all-business carrier concept isn’t quite dead yet. Silverjet found new life by getting a cash infusion, a promise of more cash, and possibly even a bidding war/buyout offer. Huzzah for them!

But the other remaining trans-Atlantic airline, L’Avion, has figured that it can survive by partnering with others. And it’s linking up with another new airline — the British Airlines subsidiary OpenSkies, which launches flights from Paris (Orly) to New York (JFK) on June 19.

L’Avion will codeshare the OpenSkies flight, but not the other way around, at least for now. L’Avion flies all-business class from Newark to Paris, while OpenSkies flies a plane with business, premium economy, and economy from JFK to Paris. L’Avion’s seats are all forward-facing cradle seats (not lie-flat) while OpenSkies has alternating front-and-rear facing 180-degree lie flat business seats.

For L’Avion’s survival, getting a codeshare with a British Airways subsidiary seems like a smart move. I’m still not sure how they can afford to sell tickets for under $1500 round trip in business class and survive long-term, but the new codeshare may have thrown them a lifeline for the short term.
