I recently flew on LAN for 4 segments in Ecuador using my AS number. The flight numbers were all XL####. The number range met the AS requirements, but the AS website indicates the flight numbers must be LA as the airline code. LAN Ecuador is a subsidiary of LAN with the separate XL code instead of LA for LAN Chile. LAN Peru is also a subsidiary and also has its own airline code - LP. I've read of people on another board getting AS miles for LAN Peru, but haven't seen that for LAN Ecuador. Anyone have experience with this?
