Taking spouse for a surprise short jaunt to Paris for Easter and London a few days after. Just secured 2 each O class (Business) tix for MIA-LHR-CDG on April 4/5, with April 9 CDG-LHR leg and returning April 12 LHR-MIA - for 100,000 miles per ticket. Were numerous 'low' award seats in early to mid-April for this route. Taxes were $334.50 because of the absurd UK tax level on J tix. When I priced the segments EXACTLY as a revenue ticket, got to over $9000 per ticket; when looked at alternate routings to same destinations/dates, priced at about $5000 each. So I got 5-9 cents per mile of 'value' from these DL award tix! Satisfactory value for the miles used!
