Arrived without incident. Staff were entirely fine.
If you fly from the UK, e.g. STN to ECN Ercan in North Cyprus, you will need to swop planes in Istanbul. You need to remember a couple of things - Pegasus offered no advice on this as they really needed spelling out. Firstly there may be a one hour time difference between Cyprus and mainland Turkey - this can cause a panic when you arrive to see your next flight is showing as 'last call'. Secondly know that Turkey to N.Cyprus is an International transfer not a domestic transfer. In other words if you arrive in Istanbul look for Transit - International. Don't go through passport control or you'll pay £20 each for the visa to 'enter' Turkey as we discovered.
A further issue was the online check-in and how fickle was the app we used. STN to ECN requires two flights and for two people that meant entering the same info four times. It took a while.
Suggest you take snacks for a longer journey unless you're ok about the on-board prices. (Mind you the airport food on the Turkish side was expensive).
