I'm looking to book ~15 pax in Y seats SYD-SIN return for early December. The pax are fairly price sensitive so I'd like to assess my options for approaching this. I could just book that many seats in one or more PNRs, and I've tried reaching out to a few travel agents but haven't heard back from despite them promising to do so. Additionally, I've looked into bulk bookings with QF and SQ but their quotes are higher than Google Flights/SkyScanner. I'm not looking to be spoonfed, but I'd be really appreciative if you guys could share any advice or if you have any particular method you like to use specifically for large bookings
