The main problem with Primera appears to be communication (or lack of it)
There is currently a 3 week response time to emails and is virtually impossible to talk to anybody from Primera. Primera have since replied to a complaint on social media informing the customer that their customer support is overloaded though they are trying to expand on this.
Added to this the constant delays and frequent cancellations using leased in aircraft and this quickly becomes unsustainable. They must have deep pockets.
