Maybe not for you, individually, or others on FlyerTalk who rely on the reservations line for rebooking and/or already have been given UA options for rebooking since the automated IRROPs engine prioritizes elite status for open seats on the later flights. But your perception of the record and what actually occurs is substantially different, as the over 500k+ invol coupons redeemed so far by OA carriers for travel this year alone paints quite a different picture than you are suggesting. Though the airports do OA rebookings at close to 3x the rate contact centers do, likely because their sole focus is getting passengers on the way, have better insight to OA capacity at their station, can liaison with OA carriers regarding space more readily, and aren't trained on other policies that they then mix pieces together from when doing IRROPs/schedule changes/voluntary changes. But regardless, your claim about the "record" is flat out wrong.
