I have questions regarding traveling with a walker that folds up. I usually take my walker and cane with us when we go on cruises as we drive to the ports and the walker is not a problem. The cruise we will be on in September will be a cruisetour - Alaska - Fairbanks, Denali, Mt McKinley and then we board the Coral Princess in Whittier. I have never taken my walker when flying. Should I take it or leave it at home? Will Delta Airlines treat it as a wheelchair or can you fly with a walker with no problems? All the information I see on their site talks about wheelchairs.
