Yolanda Reneewas stuck at New York's JFK airport:

“We were supposed to board British Airways to travel to London for a huge event, Afro Hair & Beauty Live.

“The BA agents did not communicate the computer crash issue to us until after 8:30am.

“They explained the IT crash and said they would give an update at 2pm; even went as far as saying we may not fly out today at all.

“This is so frustrating because I'm booked for the event.This is a mess!

“My first booked event out of the states and I won't be able to attend because now the flight is cancelled.

“I'm beyond frustrated and I'm exhausted. I've been up for over 24 hours!"

“I’m trying to fly back home to Dallas after a business trip.

“I will have to cancel a family event tomorrow."
