I worked in Shetland for Loganair, doing the inter-isle flights with BN2 Islanders. Quite a few tourists commented about the diminishing size of their aircraft. They'd start their journey on a widebody to the UK, transfer to a narrowbody from London to Aberdeen, an ATP or Saab 340 to Shetland and, finally, a BN2 to the outer islands. The icing on the cake was that in a number of cases every aircraft was in British Airways colours, from largest to smallest. It used to make me laugh to see the look on their faces. Some of them must have been thinking they were glad there wasn't a subsequent flight to catch - the trend wasn't exactly reassuring
