Read the passenger control literally
TRIPCARRY's flight page currently states that it supports adult tickets, with adult passenger counts in the search controls. If your party includes a child or infant, do not enter everyone as adults merely to obtain a result and then call that result a confirmed family fare. This guide assumes you can use the Korean interface; it does not establish English booking support.
Take the actual party to the seller
Before purchasing, give the external seller the travelers' actual ages or birth dates as requested through its secure booking process. Ask which fare rules apply, how accompanying passengers will be booked together, and whether baggage or seating arrangements differ. Keep names and identity documents out of public inquiry posts. A price returned for an adult-only search does not answer those questions.
Confirm the booking conditions outside the comparison page
TRIPCARRY says booking and payment take place with external sellers and does not promise an all-airline search or the lowest fare. Review the seller's final passenger details, payable amount and change or refund conditions before committing. If the search cannot represent your party, use it only as a starting point for route research, not as evidence that every traveler has a bookable seat.
