From check in to to the flight attendants, the staff of China Eastern were so rude. At check in, all staff had icy looks, and ours didn’t respond to any greetings or thank yous. Despite not at all leaning into the aisle, one flight attendant was repeatedly bolting up and down the aisle, and knocking me when passing by waking me up several times.
