first of all look at the functionality of the website as u mentioned it is a travel site, look for the similar live sites and then there are lot of information regarding Test-plan template available on the web.
Still not clear with the concept, I want to know that do we guess priorly what may be the possible errors that might occur from the user point of view. If yes then do we prepare test plan in diagrmatic format or we write it down in excel.
Can u please forward me any content that tells how to prepare test plan with an example.
Manually I can write test cases but do we concentrate on some other aspect by creating test plan.
