Top left of the site, it clearly shows “Location” which allows you to choose your location, language and save the preferences if you wish. It allows you to book with kris Flyer points and I had no trouble scrolling up or down. I think the site is a vast improvement and one others could learn from.
Part of the problem is always change. People do not like it as you become familiar with a site, newspaper etc. I’m sure give it a few weeks and you’ll come to like it. I’m betting no-one will really change their travel plans over a website design change?
With apologies to the Bard, but “methinks thou doth protest too much”.
