Looks like Swiss will be expanding their first class service through their entire long-haul network.
Service will roll out to Chicago this winter, which becomes an A340 service. Boston and Miami, both which will be upgraded to an A340 in April (BOS is already bookable as an A340, MIA will be soon), get first class service back next summer. In 2009, it will roll out to Delhi and Mumbai. In 2010, Dar Es Salaam, Montreal, and Nairobi will complete the roll out.
