Congrats on hitting 1K exactly on the nose. Nice round number.

When you said you were offered an upgrade through IAH do you mean you were offered a re-route due to an oversell? If so they would have rebooked you in a "paid" first class fare code and you would have earned 2x or even 3x the miles. LAX-PBI via EWR is 3400 miles and via IAH is 2330. If it wasn't related to an oversell situation then it would have not gotten you PQM multipliers so you would have been about 1100 miles short.
