If you subscribe to TripIt Pro there are a few reasons why your flights might not be monitored.

1. Flight monitoring for flight cancellations, delays, and gate changes begins 72 hours prior to flight departure. 

• Any changes, for plans originally submitted to Tripit via confirmation email, made prior to 72 hours need to be submitted by forwarding the change confirmation email from your email in-box to plans@tripit.com or entered manually.

2. Some of your flight details might be missing.

• Please make sure that all of your flight details are included in your reservation: airline and flight numbers, departure date, departure airport,
  arrival airport,

3. Your flight number might have changed.

• We monitor your flight information by flight number since we don't have access to your reservation within the airline's
  reservation system. Therefore, if the airline makes a change to your flight number, we won't be notified.
• Please check with your airline to verify if your flight number has changed and, if so, forward that information to plans@tripit.com.

4. Some airlines don't make their schedule available to our flight monitoring system.

5. The flight might be part of a shared trip where you are not marked as a traveler.
