Spirit has the best prices to San Jose by far......I live in the south so its closer to Ft. lauderdale where Spirit is based. Spirit does fly from Newark so check...you can usually get prices low at the last minute. Check spirit air.com As far as ticos being thieves... just as bad at your local break. Be smart and don't give anyone a reason to steal from you. Leave it on the front seat and you deserve it. Ticos are great people...don't knock'em. Theres alot worse here at home. Have fun and enjoy the Pura Vida lifestyle!!!
