I flew in Y and only within Europe. I would avoid them, the service was atrocious and the food was terrible. The stuff they were serving in J didn't look much better. I would honestly try and get on LH if possible and just do a stopover in Frankfurt. Get into the Schengen zone in Germany. The queue for non-EU and UK passports was HUGE in LIS. 5PM came around and 2 of the 3 customs officials got up and left while the queue was still bursting at the seams.
