Shangri-la - Qiaotou (Tiger Leaping George) or to Lijiang bus connection

I am coming to Diqing airport at 1.15 p.m. , after transfering to Shangri-la want to catch a bus to Lijiang and eventually get off in Qiaotou. (or is there a bus from airport to Lijiang) Please let me know what time is the last bus from Shangrila to Lijiang, how long does it take to go to Qiaotou and to Lijiang. Thanks
