The only airlines I know of running their own PSS are Emirates and Turkish. Ryanair are using Navitaire (Amadeus' low-cost subsidiary). To be honest, the cost structure is the same whether you're running it yourself or outsourcing - you don't want an absurdly high look to book ratio, or else you're just wasting server costs

I tried once Turkish Airlines. It was amazing.

I've flown with them a couple of times for leisure and once for work. Honestly find their economy food is better than most airlines' business food. The business seats weren't very good though, they're a few years behind the others

What is PSS here? I'm not familiar with this acronym.

Passenger service system, basically it's the core IT system of any travel company (airlines mainly, but also trains and hotels)
