I have a couple of questions about booking an extra seat. My wife and I are going ORD-LAS. We would book a third seat for the extra space.
* Can this be done on the website now or do I have to call?
* Can I use miles to Upgrade only our two passenger seats? The Upgrades are currently Waitlisted.
* If the Upgrades clear can I cancel just one leg of the extra seat? (Not knowing if the return Upgrade will clear?)
