Any time you want to manually submit a new travel confirmation all you need to do is forward it from your email in-box associated with your TripIt account to email@example.com. Once submitted you will receive a notification email from us once the new trip has been created or trip item has been added to an existing trip.
Remember, TripIt posts trip information by travel date. We automatically import travel plans into an existing itinerary if the dates overlap or are within a day of an existing trip. So, if you can't find your latest submission it may be in a previously created trip and not in a brand new trip.
If you submit your confirmation email from an email address not already associated with a TripIt account we will create a new account as we can only associate trip items by email address. If you do end up with multiple accounts you can easily merge your new and older account(s) into one.
If you have a Gmail, Yahoo! Mail, or Outlook account you can set up automatic submission of your travel emails to TripIt by authorizing Auto-Import for your account.
