It's clear UA is trying to direct as much sales and administrative activity to the Internet as possible, and who can blame them?? What many, many threads show is that there are still important areas where the Internet is not a viable option to get things done at all or to do so safely. Clearly, allowing handling of coupons on-line (by entering a coupon type code and certificate number) would help. It would still be necessary for the coupon to be validated by mailing it in or presenting it at check-in. There are still a lot of people who are unable or uncomfortable using the Web. If UA only made coupons available on-line to people who had an "account" with UA, it would certainly be easier. In the meantime there will be rough edges.

Does anyone know if any other airlines have this aspect (i.e. use of coupons on-line) nailed??
