Something I should have written at the beginning of the trip was the use of frequent flyer miles to help finance the trip. I accrued a good portion of the miles by using the Delta American Express card. I took advantage of the 30,000 mile bonus and no annual fee when you sign up for the card. I would charge everything to the Delta card and then pay it off at the end of the month, no interest charges. A year after the card is issued they charge an annual fee. I cancel the card, wait a year, ( use a USAIR card) and apply for a new card and do it again. It did not have a negative effect on my credit score. It cost me 180,000 Delta Air Lines frequent flyer miles plus a little under $500 (airport taxes) for the following flights. What a deal!
