Difficulty coordinating multi-leg group flight bookings to ensure travel companions are on the same flights and sit together

Summary

Travelers, especially those who are less experienced, face significant confusion and stress when trying to coordinate flights with companions who are starting from different locations or have different travel dates. They need to ensure they are booked on the same flights and can sit together, but airline booking systems and third-party platforms treat each booking independently, making it nearly impossible to link separate reservations. This leads to anxiety, frequent booking errors, and the risk of being separated during travel. Existing tools like multi-city search don't allow easy sharing or co-booking of complex itineraries, and no solution prevents one person's flight change from cascading into a coordination nightmare. This unsolved problem is particularly painful for families, couples, and groups planning international trips with different departure points.
