How old do you have to be to fly from Chicago O'Hare Intl Airport to Hainan?

The minimum age for a child to fly alone is five, but airlines that offer an unaccompanied minor (UNMR) service may have their own age limitations. Flight duration, scheduling, and layovers are among the considerations that may influence age limits. We recommend that you double-check with the airline you are booking with for travel from Chicago O'Hare Intl Airport to Hainan.

What documentation or ID do you need to fly to Hainan?

The travel and health documents required for your trip to Hainan can vary based on your itinerary and personal situation.

We always recommend checking with your airline or a trusted third party such as IATA to get advice.
