I booked flights with Aunt Betty, who I believe are a subsidiary of Fright Centre? I read the reviews but as travel was only a week after booking and I wasn’t going to cancel or need other assistance I bit the bullet. It paid off nicely (tickets to Bali, pre covid, and were $150 cheaper through them than going direct).
Would possibly have been a different story if it had been a month later during covid, with many agencies refusing refunds.
Agree with JohnK, do your research, looking at the bad reviews. Some are baseless, but a lot of them are valuable, particularly when it comes to things like ease of contact.
Airlines usually open bookings a year in advance. So offering flights for september next year should just be in the booking window now.
