I just tried to follow the CO.com instructions to get a seat on the LAX - SFO codeshare for this Sunday 3-Oct-2010 with the following results/observations:
- United IVR system <speaks english/does not understand english>
- United CSR <barely speaks english/does not understand english>
^
- Secured E+ seating!!!
Next time I will try to do the same via United elite line and see if its any better.
