Running gîtes all one is looking for is enough clients to fill the place. So for us it is about 24 bookings as some are for two weeks, and we also block out 8 weeks for our own holidays. It is not the sort of business where one has flexible capacity, so more demand is not very useful to us.
There are different models where Air could be more appropriate.
We pay €175 a year to be listed on 4 direct booking portals, with no extra commission. So far that has brought us the customers we need and the summer is often fully booked by end January. By not using Air our prices are lower than the competition, which also helps attract custom.
So we see no reason to pay several thousand in fees to them.
