I traveled with my daughter and granddaughter who had been in a horrific car accident. They were in the hospital for a week and had just been released. We were on our way home and the staff was amazing. They were patient and helpful and so kind. We had special needs to lift my granddaughter from her wheelchair to her seat and they listened to our instructions making her pain less. Thank you so much

Delta is my airline of choice because of its excellent customer service, good choices for flights, "on-time" policy and reasonable prices. I fly Delta whenever possible for both domestic and international travel.
