We have found a strong air current ahead for the next forty miles or so. Passengers are therefore strongly advised to remain in their seats with their seat belts on for their own protection and to avoid use of the restrooms for the time being, if at all possible. During this time, young children should be firmly fastened into their seats. Please observe these precautions until the seat-belt warning sign has gone off. Lunch will be served after we have passed through the air current zone. Thank you.
