This is wide open for May and June, 2010 only. You fly from DC to either Miami or JFK on American and then connect to LAN to Lima.
5-day minimum stay. Last day to depart on this fare is June 17. Fare basis is QLESP516.
Non-refundable, non-upgradable (though I’m not an expert in LAN’s upgrade rules), but will earn full miles if credited to American.
