Google will blame Ryanair's web designers and they'll blame Google!
Good website design should involve checking that the site is compatible with all common browsers. Ryanair's designers seem not to have noticed that some functions won't work under Chrome, so it would be easy to blame them.
However anyone bringing a new browser onto the scene (particularly in a blaze of publicity, as Google did with Chrome a few years back) would also be wise to make sure that their new product supports all of the requirements of current websites. Google clearly haven't yet got a product which does exactly that.
You're not the first to notice the problem

but, until Google upgrades Chrome (or Ryanair modify their website) you'll have no alternative other than to use a different browser. I'd recommend sticking with Firefox but, if you want a lightweight browser (which offers the speed of Chrome with the reliability of Firefox) try K-Meleon:
