Deals
In searching for the best deals, inmy case out of ORD, I am finding that WN cities are those which UA is competitive on a one way basis. THis being the best use of the o/w fares and the e-certs.
Not sure if UA is being competitive out of IAD to match all the BWI WN flights; but, they should at least match the IAD WN markets.
MODS - suggest removing the "X-mas day only language in the header. This fare seems to survive well before and beyond the Holidays.
