Take a look at Roatan and Utila. Continental fly from Houston to Roatan and then Atlantic from Roatan to Utila round trip from Houston to Utila around $600. My preference is Utila, great diving and great pricing. Look at
www.deepblueutila.com
I'm planning a dive trip in Sep and was considering Roatan. Since I'm coming from the SF Bay Area, my focus is getting on and off the plane as quickly as possible. This is our first trip since our 10 month-old was born.
Can I ask you to tell us why you liked Utila over Roatan? I'll do a little more research before I commit to airline tickets, but if you've got strong beliefs over one, I'd love to know about them.
