Hey guys, found this great deal from Aeromexico Airlines
http://aeromexico.com/us/welcome.html. If you are coming to San Jose Labor day weekend ( Wednesday 8/27 - Wed. 9/3) and don't mind a little layover in Mexico City, you can fly for $479.61 rt. that's is about as cheap as I have seen. If I can be of further assistance, please let me know. Thanks.
Sincerely,
Sid
