I booked a flight for myself and mrs globalste back in Feb from SFO - LOS on Sept 27th.

As im *G i could select Row 5 (economy+) and picked row 5a and 5b.

When i looked on expert flyer though yesterday, it shows only 5a and 5c exist??

Any ideas?

Is this for US Air or United?

US Air recently changed the First Class seats from 1A,1B,1C & 1D to 1A, 1C, 1D & 1F for all segments including the AWA flights.

This may be the issue you are seeing.

I would go to the USairways site and check you reservation under "Manage Reservations" - It may have been changed to reflect the new seat numbering or this may just be another issue of US Airways FUBAR.
