I enjoy flying Delta Airlines. It is a good air carrier and offers a large number of flights to basically anywhere you want to go. I especially like the large number of non-stop flights that are offered. These are a real value because they get you where you want to go faster, and it's also a lot more convenient.
I was able to use my frequent flier miles for a dream vacation to Hawaii. We had to break up our trip into three legs, which wasn't the best, but hey, we only paid the $20 service fee to go all the way to Hawaii, so I wasn't complaining.
Delta usually provides snack and beverage service on most flights. They are also willing to help accommodate any special needs. Delta staff members have always been very friendly to me. Delta is my favorite airline.
