Copa and TACA poised to join Star
By Brendan Sobie

Both of Central America's leading carriers, Copa and TACA, are poised to join Brazil's TAM as new members in the Star Alliance.

...

Copa chief executive Pedro Heilbron, meanwhile, said on the sidelines of the forum that the Panamanian carrier has decided to leave SkyTeam and is in exclusive talks with Star.

Heilbron says Copa has no "commercial choice" but to leave SkyTeam because its main partner, Continental, decided earlier this year to leave SkyTeam for Star. Continental sponsored Copa's entrance into SkyTeam. Continental is scheduled to formally leave SkyTeam for Star late next year but Heilbron says "we have some time" to decide what it should do.
