Saturday I found saver availability MSP-IAH-ACA with an overnight in IAH that worked great for our plans. I transferred 70K UR points to UA to complete the purchase. While purchasing, I opted to apply for the MileagePlus Explorer card which ended up not being approved until Monday. Went back in and completed purchase Monday - had to transfer 4K more since the price went up since Saturday. Grrr.

I decided I would watch the fare for the next 24 hours to see if it dropped back down to rebook. That flight option has disappeared for that day of travel only. Can't find it anywhere - but no changes have been made on my ticketed reservation. Seat map of my flights shows plenty of availability.

Should I be concerned about my plans?
