Route & Airline
The Chicago to San Juan route connects the Midwest directly to Puerto Rico's capital, making it a convenient escape for East Coast-bound travelers. Frontier operates this route with one stop, keeping things straightforward for budget-conscious travelers heading to the islands.
Travel Tips
March and June offer great weather for beach time, though June marks the start of hurricane season—pack an umbrella just in case. Puerto Rico uses the U.S. dollar, so no currency exchange needed for American travelers, but do check travel.state.gov for any current entry requirements before booking.
