No bueno on CPU with myself and nephew both GS on SFO-IAD. Flight a bit delayed (#517) but probably 13 GS boarded with us. Number 1 and 2 at check in but dropped to 3,4 at boarding. We saw names jump us a figured they applied instruments as it looked bad. Oh well got good E+ seats. I figured this would be an easy cpu on a wed. well figured wrong. Zero luck with cpu's on this route this year. Nephew same with 3 RT's and zero upgrades in and out of IAD. Use instruments next go round.
