Worth knowing about San Juan
- San Juan's Tren Urbano does not serve the airport, Old San Juan or Santurce: it is a single 16-station line covering only part of the metropolitan area.
- Puerto Rico is an unincorporated US territory using the US dollar and the +1 North American Numbering Plan, so numbers dial like the mainland US.
- Puerto Rico is on Atlantic Standard Time (UTC-4) year round with no daylight saving, one hour ahead of US Eastern Time.
- San Juan's second airport, Isla Grande, is mainly general aviation; its scheduled flights are Air Flamenco and Vieques Air Link services to Vieques and Culebra.
- SJU handled 13.6 million passengers in 2025, making it the busiest airport in the Caribbean.
