The trouble with the loco model is that it combines often unsustainable fares with a high level of income from ancilary fees. Smart travellers want to reduce these fees & if profitability depends upon boosting them - well management have to find ways to boost income from them. Ryanair used to charge for using all types of credit & debit cards with an obscure exception (I forget which). When their punters acquired this type of card guess what - they changed the card that could be used for free! We see this with having to pay to sit together. Could it be the same with check in? Personally I would like to see a shift away from ancilaries to slightly higher base prices - not entirely, it still makes sense to charge for alcohol and a second hold bag, but so that you feel that you can fly at the basic rate. However, the way I think may not be representative of the population as a whole.
