Greetings dog lovers,
Seeking advice/things to consider when traveling with dogs in the airline cabin. The trip goes from San Diego to Glacier Park area of Montana--winter trip.

Our 10-year-old cairns have never traveled in a plane and we are weighing the option of 2 1/2 days in a car (1400 miles each way) versus 4-5 hour airline trip(one way), with plane change in Salt Lake City/brief stopover. Air travel is obviously very quick, but we don't have a clue of the affect of air travel on our dogs.

They would be in cabin with us -- we will not check them via baggage with the airline and it's too cold this time of year for the airline to check them regardless. We travel on Delta & have the information on appropriate soft
container/carriers.

Your sage advice is appreciated.
