Family & International Fare Guides
Family international airfare where seats-together rules, child fare codes, baggage policies, and mixed-carrier routing all move at once.
Family-of-four international compounds every airfare variable at once: seats together, child fare codes, baggage, mixed-carrier routing. The guides below run that math on real itineraries.
Decision rules in this hub
Seats together on long-haul
Basic-economy seat fees: $25–$75 per seat per leg. Family of 4 with one connection each way → up to 16 fees ($400–$1,200).
Child fares vs basic economy
Legacy carriers offer 10–25% child discount on PUBLISHED fares — not on basic-economy or promotional buckets.
Baggage compounds
4 travelers × 1 bag × 2 ways at $60–$100 = $480–$800. Often exceeds the gap to a fare bucket that includes a bag.
Mixed-carrier risk
Outbound and return rules differ on bag fees, seats, and missed-connection protection. On locked dates, single-carrier is worth $200–$400.
