Aerosvit, otherwise known as Aerosh*t.
Worst airline I've ever flown. Did JFK-KBP-TLV and back with them last summer and it was not a good experience. Flying in to JFK during peak hours? Expect to spend 30-40-60 minutes circling about in the air with no explanation as they get the absolute lower priority when it comes to landing clearance.
Add rude service and dirty airplanes and I'd rather take a sailboat to BKK.
