I was looking at Frontier Airlines #857 for December 5, 2010 and the flight path has the customary “green” line from Denver to Phx. However, next to it are blue “dashes”. The dashes, at one point in the flight, veer way off the green course. What does this mean?
Just a nervous flyer here. I’ll be on this flight next week.
Thank you for any insight you can give.
