Cheap flights to Puerto Rico 

Puerto Rico is the most vaccinated spot in the US with 74% of the population fully vaccinated. Plus, since it’s technically part of the US, there’s no passport required for US citizens and no Covid test required for returning to the mainland, making it a stress-free way to get some Caribbean sun and sand.

With miles of sandy beaches, rainforest, and a unique culture, there’s so much to explore, from salsa dancing in the capital and largest city, San Juan, to lazing in the sand on one of its dozens of cayes and islets.
