Silver.
Booked a November CLE-MCO/RSW-CLE for $246
The instant upgrade offer was $159 for the CLE-MCO segment. Basically the same as the upcharge to an A fare @ $395. No TOD there. Declined.
After res was ticketed, checked upgrade offer and it was ~$850 for the CLE-MCO segment. Why does UA punish those of us who don't accept the initial offer, but might think twice? Seriously, $850 to upgrade a 2.5 hr snack flight? I'm pretty darn sure the kettles will be getting $89 offers at OLCI....
