A few years ago LP's parent Company tried to do a European Version of LP. It never did seem to get off the ground.
I suspect this is a new programme to gain carriers that either could not get into LP, or didn't want to get into LP!
The fact of the matter is that everytime a new member can join LP, the existing members must all agree.
In the past this has kept some Asian carriers who have routes to Latin America out of LP.
Also lets face it a Airline like MALEV Hungarian would not have much in common with the other LP Members, so this programme is probably geared to a more international sector, to gain carriers like Malev, Turkish Airlines, Philippine Airlines Ect.!
