I won't fly RhineAir again EI-BUD. They lost baggage and nearly made me late with their poor checkin procedures a few years ago. Add to that the aggressive nature of their management and they are what is worst about modern airlines to me. If I wanted to fly cheaply, I might fly EZY again, although I never manage to get the cheap flights (:-(), but RhineAir is just ghastly.
Now Türk Hava Yollari (Turkish Airlines) are just the business for me at the moment. I have flown 4 trips with them in the last 2 weeks, 2 longish (STN-IST), 2 short (IST-DLM) and they were great. Nearly as cheap as the ghastly RA, but with decent check-in, decent food and drink, friendly staff and 4 safe landings. Mind you, the app to IST at night was a bit bendy, and I was not too sure about darting through the cloud gaps just north of DLM just above the mountains ...
