No problems whatsoever with Air Linker. These guys are on-time, with clean and comfortable cars. Unlike most Calgary taxis, the Air Linker sedan we got was comfortable, quiet, upscale, came with a couple bottles of water, and didn’t have junk lying around. The driver was professional and pleasant. You can book over email, which is kind of nice. They guarantee to be on-time. The price increase over a regular Calgary cab is pretty minor. it was about $ 10 more for us when we went to the airport, roughly a 45min ride. Well worth it.
