A Seattle woman, Crystal Kim, 62, did not clarify the medical test of Korean Air and hence she was kept from boarding a flight to South Korea on the occasion of Mother’s Day, which was on Sunday.

Delta Air Lines (DAL) began with the increase on Monday on its premier class and last-minute fares, with hikes up to one hundred and twenty dollars for a round-trip ticket.
