Rumor of only 737s is not true. Right now guys/gals returning from furlough are going A-320, 737-300, or 757/767... crap shoot. They used to pick pilot seniority in the clases by last four numbers of SSAN... but no idea what this time around. I don't think UAL has a plan on what jets to fill new hires yet... but alot of the returning furloughees who got 737s and A320s with 3 year freezes are not happy... so policy might change. My recommendation is take the 737 or 320... good experience for a new hire... lots of flying.
