JFK - FCO

Check in staff were very nice! No wait to check in. However, the flight was delayed and the cabin crew spoke English with heavy accents that were hard to understand. Unfortunately, the bathroom was dirty and smelled VERY bad! There was garbage and pee on the floor and nobody cleaned it up. Also, on the flight from Rome to Bari, the female flight attendant spoke so fast in English and Italian that it was impossible to understand anything that she said. Real mil would be preferable to powdered mil in the tea/coffee. Besides this, the plane was comfortable.
