I am the proud owner of award tickets NYC -> CMB -> BKK -> NYC this summer. The TPAC flights are all in business, but some of the shorter positioning and intra-Asia flights are in economy. Just for fun, I'd like to calculate the approximate cost, in dollars for these itineraries. I know that the same stops (cheapest routings) are about $2,300 in economy and $5,300 in business. None of the search tools, however, allow me to specify some of the flights in business and some in economy to actually reflect what we're flying. Is there any way I could get an estimate of the price to buy the mixed-cabin itinerary we're on?
