Seriously think people are putting too much emphasis on the captcha. It's no more annoying than navigating through the booking and avoiding the optional extras. I find it amazing people will go to another website of another airline and start the whole booking progress again. Is it not just as easy to tap in a few letters. It even tells you the letters out loud if you have problems. Craigslist uses captcha and it doesn't do them any harm. Is it really that hard?
