I wish I had when changing planes at Doha en route to NZ. By myself and waiting for my new hip, I couldn't walk fast.
I still had miles to walk, was sleep deprived and had just realised I'd left my phone on the first flight when my flight was called and I was getting agitated.
Luckily I was spotted by a driver of a buggy who told me to climb on and he got me to my gate just in time but I would never want to repeat that stress.
Good luck to you!
