You have the right to deduct ordinary sales taxes on the purchase of a house on Schedule A, if you itemize. Other available deductions are real estate (property) taxes, points you pay to get the mortgage, and mortgage interest.
Still, the airlines that you do have to choose from are high quality, major carriers such as Delta, American Airlines, US Airways, and United. Many cities throughout the U.S. provide direct Palm Springs flights, which allows you to spend less time in the air and more time enjoying the warmth of the desert.
I had planned to fly on Allegiant Airlines, but they no longer had direct flights from Palm Springs to Sacramento area, and Alaska Airline did. Over all it was a nice trip, but Allegiant Air had been less expensive which would have been a bonus.
