Is it cheaper to book open-jaw or separate round-trips?

Open-jaw is usually cheaper for 3+ cities because you eliminate backtracking flights. For 2 cities only, compare both options - sometimes two separate round-trips cost the same but offer more flexibility.

Can I earn miles on open-jaw bookings?

Yes, you earn miles for each segment based on distance and fare class. Book with one airline alliance when possible to concentrate your miles in one program.

What happens if one segment gets cancelled?

Each segment is treated separately for cancellations and rebooking. This is why booking through one airline or alliance is better - they'll help reroute your entire trip instead of just one leg.

Should I book all segments at once or separately?

Book together if using traditional carriers for better rebooking support. Book separately if mixing budget and full-service airlines or if the price difference is over $300.

How to Book Open-Jaw Flights for Asian Business Travel

Book open-jaw flights by selecting "multi-city" on airline websites or using tools like Google Flights' multi-city search. Start with your hub city (Tokyo, Singapore, Hong Kong), then add each destination as a separate segment. Book 3-4 weeks ahead for business routes, and consider airline partnerships for consistent service levels across Asia.

Map your business route. List all cities you need to visit and identify the most logical routing. Choose a primary hub (Tokyo, Singapore, Hong Kong, or Seoul) where you'll start or end. This becomes your "jaw" - the city that appears only once in your itinerary.
Use multi-city booking tools. Go to Google Flights and select "Multi-city" instead of round-trip. Enter each leg separately: Origin to Hub, Hub to City 2, City 2 to City 3, etc. This shows you real combinations airlines actually fly, not theoretical routes.
Check airline alliance options. Search Star Alliance (ANA, Singapore Airlines, Thai Airways) or oneworld (JAL, Cathay Pacific, Malaysia Airlines) for consistent service levels. Book directly through the primary carrier's website for better support when changes are needed.
Compare with separate one-ways. Price out each leg as individual one-way tickets, especially for budget carriers like Scoot, Jetstar Asia, or AirAsia. Sometimes this costs 20-30% less than traditional multi-city bookings, but you lose rebooking flexibility.
Book and manage your segments. Complete the booking 3-4 weeks ahead for business routes (earlier for peak seasons like Golden Week or Chinese New Year). Save all confirmation numbers separately and check in for each segment individually - they're treated as separate flights even if booked together.
