I’ve flown Pegasus a handful of times between Turkey and Europe and always walked away thinking the same thing: it’s fine, if you know what you’re getting into. You can fly for the cost of dinner, but everything else is à la carte, and if you miss the small-print fees like paying to print your boarding pass at the airport, it adds up fast. The flights themselves have been punctual and the planes are newer than I expected, but comfort is minimal.
Honestly, for a quick hop and light pack, I’d book them again but never with a tight connection.
