Choosing Family Seats on West Air and China Southern Booked via Trip.com
You can choose seats before check-in opens on both West Air and China Southern, even when the Trip.com order page suggests you have to wait. On China Southern, advance seat selection for standard economy is free on domestic flights, and the seat map usually opens days before departure. The reliable path is to manage the booking inside Trip.com: open your order, tap Check-in and Seats, then Reserve Seats, and place your whole family together while most of the cabin is still open. China Southern often does not offer online check-in on some domestic routes, so if the seat map will not load early, the next dependable window is online check-in, which opens 24 to 48 hours before a domestic flight. That is also when an unselected passenger gets a seat auto-assigned, so acting earlier keeps the family together. West Air is a budget airline and behaves differently: on its lower fares, picking a seat in advance can cost extra, and free selection may only open at online check-in 48 hours out for domestic travel. For the Shanghai to Chongqing leg, set a reminder and select seats the moment that window opens. At the airport, China Southern may still offer a paid extra-legroom upgrade at the counter, which is optional. If an online seat map ever refuses to seat all of you as one block, arrive early and ask the check-in agent to assign adjacent seats directly instead of waiting for boarding, when the fewest pairs are left.

Why this is different for foreign visitors
Chinese full-service carriers like China Southern give free standard economy seat selection on domestic flights, but third-party platforms sometimes hide or delay that option behind their own order flow, which makes travelers think they must wait for check-in. Budget carriers such as West Air monetize advance seats on cheap fares. Domestic online check-in typically opens 24 to 48 hours before departure, and a passenger who never picks a seat is auto-assigned one at that point or at the airport counter.
Common mistakes to avoid
- Assuming the Trip.com message means you genuinely cannot pick seats until check-in, instead of trying the seat map under your order.
- Treating West Air like a full-service airline and expecting free advance seats on a cheap fare.
- Waiting until the final boarding wave to ask about sitting together, when the fewest adjacent seats remain.
