There is an unadvertised price reduction on fares between New York City and San Juan, PR. You can now get a round-trip ticket for $185 including taxes! You can find a calendar of fares on Fly.com here. The best fares seem to be in May and early June. Most of the dates I checked were coming up at $245 which is still a great deal.
I love Puerto Rico. I lived there for a year and a half in my early twenties. Here are my posts on some of my recommendations for Puerto Rico. Also if you’re looking for a more secluded Puertican vacation, consider visiting one of the smaller islands of Puerto Rico – Culebra and Vieques. Feel free to send me any questions you might have on Puerto Rico.
