UAL.COM's "new" senior discount electronic certificates (
www.ual.com/gtcseniorfares) have a rather strange restriction:
<font face="Verdana, Arial, Helvetica, sans-serif" size="2">At least two passengers on the reservation must be over the age of 62 by the date of travel to qualify for the senior discount.</font>
Does this mean seniors don't get a discount unless they travel in pairs? Oh, I can see a P.R. disaster in the making: "Latest slap in the face for widows/widowers: United denies senior discounts to surviving spouses."
Note that ticketing at a CTO instead (assuming you can find one), the "take-the-grandkid" rule still applies:

<font face="Verdana, Arial, Helvetica, sans-serif" size="2">A companion of any age, traveling with you on the same itinerary, is also eligible to receive the 10% discount.</font>
I wonder what the AARP has to say about this...
