I insisted there couldn't be anything wrong with the res, and they just ran ID + BP, and it worked both times.
How is Clear recognizing me and my res, TSA also works off my ID, but TSA not off the Clear scan?
Is this a last minute reservation, or same day change? Clear scans your BP to validate same day travel, and uses biometrics to authenticate the traveler. However, TSA is working off of data sent by the airline, and it's a known issue when there is a same-day booking/rebooking when the airline data is not synched with TSA. The fallback is the old school ID and BP.
