Wow five hours in YXE...Lived there from 2007 to 2010, great airport to fly out of, but not for layovers....no MLL, no nothing really, small Tim's in teh centre and a nice clean and open airport with free wifi but really fve hours....you will go nuts unless you sit at the open eating area, plug in your computer into the one wall outlet on the side with a table and facebook for five hours. Take a cab to market mall and you can walk it or downtown along the river.
Your in Saskactwans largest city 240,000 people, clean and friendly city, enjoy the core as the airport will certainly bored you to dealth and you will b ina CRJ 200 to Denver and that two and half hour flight will also bore the crap out of you.
