In view of your latest post what you have planned is the best routing with the best availability. While the equipment used on the MSP LHR route is smaller than other cities you should most certainly be accommodated in the coach cabin with over 90 seats available at this time. You might even snag a business class seat if everything stays right as it is now. The DEN MSP portion is the best with availability as you have planned - about 25 seats overall but it is the last flight of the day to make the LHR connection. The other DEN MSP flights do not have as much availability but will more than take care of the connection time. MSP airport has a lot of interesting shops to browse and great restaurants to get a bite to eat before the trip over the pond. So a semi-long connection time would be better than a rush to the gate if your DEN MSP is delayed. Tough decision - I would try for one of the earlier DEN MSP flights and coast with the connection time. Best of Luck ! Your non-rev listing is JAN/P with 10/24/89 seniority ?
