Haikou

The big-ticket item is genuinely free: Hainan Airlines covers a 1-night stay at a 3-star hotel in Haikou. But "free" has edges worth knowing: you still typically pay for meals beyond anything included, any city or tourist tax, and a transit-visa fee if your passport needs one. Compare the total fare too: adding a stopover doesn't always cost the same as a plain connection.

Passengers flying Hainan Airlines on a ticket issued by the airline, with a qualifying layover in HAK between 4 and 72 hours. Eligible booking classes: see airline. One free night at the Haikou Meilan International Airport Hotel for international/regional transit passengers (non-Haikou-resident ID) with an onward international/regional flight within 72 hours. The free room (or a RMB 100 dining voucher) applies when the connection is more than 4 hours and up to 72 hours; a connection of 4 hours or less gets only a RMB 60 voucher. Free rooms are capped daily in peak season, first-come first-served. Hainan's 30-day visa-free entry (government policy, 59 nationalities) applies separately.

Your connection in HAK should fall between 4 and 72 hours. Two things travelers get caught by: flight-search sites usually show the shortest connection by default, and that's often too short to qualify. You may need to deliberately pick a longer-layover flight. And the layover shown isn't all usable: clearing immigration and any baggage steps eats into it, so give yourself comfortable margin above the 4-hour minimum.

Stopover programs are run by the airline, so the safest route is a ticket booked directly with Hainan Airlines on an eligible fare. Award and miles tickets, and bookings made through online travel agencies or other third-party sites, often follow different rules: sometimes they don't qualify, sometimes the stopover has to be arranged another way. Before booking like that, confirm directly with Hainan Airlines that your specific ticket type is eligible.

To leave the airport for your stopover you must meet China's transit or entry rules, and this matters before you even fly: if your passport requires a transit visa and you don't have one, the airline can deny boarding. The good news: many nationalities get visa-free transit, visa-on-arrival, or a quick e-visa, and some stopover programs include the transit visa. Select your nationality on this page to see the exact requirement for China, and arrange any visa well before departure.

Airlines do sometimes adjust schedules after you book. A change can shorten or lengthen your layover. If it drops the connection below the 4-hour minimum, or past the maximum, it can affect your eligibility. If you get a schedule-change notice, re-check your layover against the program's window and contact Hainan Airlines to rebook or re-confirm the stopover. It's worth re-checking your itinerary a few days before departure.

On a single Hainan Airlines ticket, your checked bags are normally tagged straight through to your final destination, so you head into Haikou with just your carry-on, and your luggage continues on the onward flight. You'd only collect and re-check bags if part of your trip is on a separate ticket. If you'd like a checked bag with you for the overnight stay, ask Hainan Airlines when you arrange the stopover.

Up to 3 days. You can extend your layover without paying additional airfare, as long as it fits within the program's rules.
