DL 1542 (1055pm SEA-JFK) departed from B9 on Sat 7 Dec ... when I booked SJC-LAX-SEA to finish up the MR, I decided that 37-min connections were too risky in terms of getting overhead space (esp off a CR9 at LAX where I'd most likely have to wait for a pink-tag rollaboard) and decided to take advantage of pay-with-miles for the buyup to G ... DL 2410 from LAX parked at S7 at about 1030 which indeed would have been problematic; however it turned out to be moot as I had been able to SDC to the earlier SJC-LAX and LAX-SEA flights (and kept FC seats on both)
