I recently took a Cathay Pacific flight to Miami, and I had an amazing time.I had the chance to use the Cathay Pacific mileage upgrade service, and it did not let me down. I appreciate any chance to improve my travel experiences, and this one did not disappoint. The selection of Cathay Pacific for my journey was made with ease and clarity, and I am glad I did. Getting around the upgrade area and the entire process makes my journey less stressful and more comfortable.
