TripIt does not remove user trips unless a user has authorized the removal from their account or someone with editing rights to that trip authorizes removal. Unfortunately we can not view history for deleted trips nor can they be restored.
If you can no longer find a trip in your account there are several possibile reasons.
Multiple Accounts: Occasionally users have more than one TripIt account (with different email addresses associated to each) and the trip is located in an account the user is not viewing. This is the most common reason users cannot locate their created trips. If you do find you have multiple account you can merge them into one single account. Please see our Merge accounts help page.
Time Out: The trip may not have actually been created if you had not made incremental saves. For security purposes (many users sign in to their site on company, internet cafe, etc. computers) our site does sign out after approximately 20 minutes. To avoid this you just need to make incremental saves as you go along. Every time you save the time out clock starts again. Similarly for trips created on our mobile apps the items need to be physically saved.
Editing Rights: If you provided editing rights when you shared the trip that person has the same ability to edit/delete a trip as you. Some time users inadvertently cancel a trip (usually when they are trying to edit it or remove it from their account).
User Deleted Trip: Unfortunately we can not view history for deleted trips nor can they be restored. The good news is you can resend your original vendor confirmation emails to firstname.lastname@example.org and we will repost those trip items in a new itineary.
