Yet more thanks for Çelebi arrived from the President of the United States, Barack Obama. Obama's flight team received ground services from Çelebi Ground Handling during the İstanbul and Ankara visits of the president in April. The USA President's airplane, Air Force One, had already thanked both the ÇGH İstanbul and Ankara Station personnel for their quality service and the successful operations they performed. Another thank-you was received from the President's Communications Office for the experienced services rendered for Air Force One when President Barack Obama left our country after completing his meetings in Turkey.
