Scottish media have reported recently on the significant impact the Ryder Cup at Gleneagles will have on the Scottish economy. While I am generally cynical of government produced figures which are often skewed for political purposes, I can speak knowledgeably about the impact of golf travel to Scotland for 2014.
Historically the Scottish golf travel season is at it s peak during May to early September. The annual closure of the Old Course at St Andrews low rates discount hotels for the second third weeks of September followed closely by the Dunhill Cup Matches effectively puts a soft exclamation point at the end of the busiest summer weeks.
The Ryder Cup during the last week of September in 2014 has effectively erased that exclamation point and moved it into early October. Importantly, whereas many American golfing visitors to Scotland make playing the Old Course at St Andrews their top priority, during late September attendance at the Ryder Cup supersedes the Old Course and that increases demand and availability exponentially.
8,000 spectators at £3,000  each which includes accommodation, food beverage spending, gifts, transport, etc. of which a portion - 2,000 golfers spending £3,000 each on golf trips that are added onto their Ryder Cup visit = £30M UKL. Obviously not all of these funds flow into the Scottish economy (e,g, Ryder Cup tickets) but also remember this is just a portion low rates discount hotels (less than 25% of the spectators).
Air travel 8,000 will spend on average $3,000 per ticket for various cabins on aircraft  = $24M in airline revenue. These monies are not coming to Scotland other than spend through airports, extension of seasonal airport jobs, etc.
