I use my miles in various ways. Sometimes for my own flights, both domestic and international - usually in premium cabin though occasionally in coach. Sometimes for others to take trips they otherwise would not have taken. Sometimes for both myself and others to take trips together. One of the most fun ways I used miles recently was for a group of 9 of us to fly from the lower 48 to Alaska round trip. It was for a group of 7 teenagers I had been mentoring. Great trip and great memories for all.
