We departed on time - we upgraded at the airport to business class, great thing to do. We enjoyed use of the lounge at Heathrow Airport and then boarded easily. The seats were comfortable and perfect for a night flight - slept all night! Breakfast was adequate. Arrived in Bogotá feeling fresh - unfortunately the onwards flight with Avianca to Santa Marta was delayed for 2 hours :(. Would defiantly use Avianca again to travel from Heathrow.
