These weren't NW-issued. Expedia, typically. And yes, I fax before mailing. I mailed in the half-dozen from last year after faxing them got no response within a month. Since I'm out-of-country, I don't know whether I'll try to fax this one in, may just mail it.
And the "Q" will take about a week to go away - or at least, the "Q" on the outbound segments did. I'm not worried about it. I just want that final segment to show up.
