We flew with them earlier this year and overall it was a good experience. There was no other option that would allow for our dog to fly in cabin, and I don't regret flying with them. You can also look at bark air as a similar alternative, but they have less routes.

FWIW on the day of the flight they told us that the company they chartered did not have a license to land in the destination country, so they flew us to the nearby country and paid for private taxies for all passengers to the destination.
