Traveling website full walkthrough flow for guest check-out flow. When I started this assignment I love to create this flow for my users, who come into the site and search the deals and the frustrated to go back and then sign in and again they do full process search to checkout and don't want to give the pain to my users, so I just create this full flow how they book there flight only in just a few minutes without go back.
