Grandmaster Arjun Erigaisi slammed British Airways after what he described as his worst flying experience. "Involuntarily downgrade, rude employees, no communication, bags delayed for...48+ hours...It's frustrating," he tweeted. He added, "Messages, emails, forms...everything submitted. It’s been 2+ days and still no word. I don’t know how an airline can afford to treat its customer in this way."
