Plane Tickets

airlines question?

I have to find the price of airline tickets roundtrip from San Diego, CA, Cardiff, UK which is in Wales. I need a round trip price for each season, ie spring, summer … and the need for two different airlines northwest. doen't matter of costs. The trip should be 6-7 days duration in each season. I need the dates that you go into every season as well.

Only was found no other airline Northwest: $ 1448.98 Summer $ 1143.98 KLM Airlines 7/3/06-7/10/06 Fall 10/03/06-07/10/06 KLM Airlines $ 1051.98 Winter 01/03 / 06-01/10/06 KLM Airlines U.S. $ 1126.98 Airways, KLM / KLM $ 1039.98 Spring Airlines 04/03/06-04/10/06
