You're travelling to Costa Rica (CR). Your home cellular plan may or may not include data abroad — check your carrier's international options before you fly. An eSIM is a low-commitment alternative if your plan doesn't cover the destination or charges high roaming rates.
The US State Department publishes these advisories for your route. Costa Rica: Level 2 — Exercise Increased Caution (as of 2026-04-02). Review the country page for the specific areas and risks flagged before you go.

Sign in (free) to personalize →Costa Rica requires proof you'll leave before they let you in. At check-in the airline often asks for this — without it, they can deny boarding because the carrier becomes liable for flying you back. Easiest fixes, in order: (1) book a refundable return or onward flight, (2) use a one-way bus / train ticket out, or (3) buy a temporary onward-ticket reservation through a service like OnwardTicket. Have whichever you choose printed or on your phone before you reach the counter.
