Delta's pre-select meal option will soon be available on all Delta One routes, expanding the food option to more business customers traveling between the US and Europe, Middle East, Africa, Asia and South America. Beginning Dec 6, pre-select meals will be available in more than 200 markets around the world, marking a relatively speedy expansion since its initial launch in March. Delta One is the airline's latest update to its business-class cabin that features lie-flat beds and sliding privacy doors. The pre-select meal program is part of Delta's multi-billion dollar investment in the overall customer experience, which heavily focuses on on-board personalisation. The pre-select option allows passengers to pick their meal of choice ahead of time. <br/>
