According to the November category list, the bottom of each category has pilots over 10,000 in seniority, including the A330. The A330 has 173 total FOs in SEA, with number 163 being in the 8900-ish area, and the last three being over 10,100 in seniority. The 757/767 (ER) in SEA has 164 FOs, having the bottom 14 over the 10,000 mark, and the bottom guy being close to 10,700. There are rumors of adding a few more Asian cities from SEA possibly, which would increase the need for pilots up there. One of those could be Tokyo Haneda on the 767, if DL can trade the current DTW to Haneda slot that is not doing very well currently. There is a push to try to trade city pairs to that other airport. The other current West Coast bases are LAX and SLC, and SLC on the 320 is not that senior. (SLC also has the 737 and the 757/767, whereas LAX has the 757/767 and the 737, not the 320) Good luck.
