So I ticketed a SFO-SNA trip using a $150 voucher on Friday. I bought a routing that could potentially have a lower price if an e-fare was offered for it.

Sure enough, last night the price drops (about $41). But even though the itinerary is identical you can no longer refare to the lower fare (through united.com or through Reservations). Basically the e-fares can only be accessed by booking through the e-fares link on united.com. In fact, regular bookings on united.com won't pull up the e-fare - you have to go through the e-fare link.

This means that other booking systems like Orbitz, Expedia, Travelocity etc can't see the lower fare either.

It's kind of a "too bad" thing. But FWIW there is no way to use a voucher for a ticket booked through the e-fare link anyway (and had I not ticketed it last Friday the price would have actually gone up another $43).

I haven't bought an e-fare in ages - is this something that's old news? Seems kind of silly not to advertise your lowest fare. Also muddys the waters for applying the "lowest fare guarantee on united.com" no?
