Could fix their booking.

I booked a flight with Mango and I thought all was well tille I checked in and was told that they were using a small aircraft so they asked if they could change my flight, I had no problem with it. I have not a lot of issues with them, just that maybe don't overbook if you are gonna move people based on a small aircraft and also I was surprised to know that I was being moved to another airline completely, you're losing credibility.

I was glad though to learn that with the other airline I was bumped up to priority boarding, I appreciated that, it was a good gesture.
