Certainly some of the extra charges are just way over the top. Remember how we were encouraged to book on line with a small discount if we did so? Now we have to pay for the privilege!
Can you imagine your local supermarket adding 10 pounds to your shopping bill for choosing to shop with them? It's all just become insane.
I believe that the all-important high yield revenue generating customer (the late bookers) will eventually abandon the LCCs and return to the legacy carriers (if there are any left). This will force LCCs to rethink their product (or market model, to use PAXboy's more apt term) if they want to survive. It won't be too long before you see a two class cabin on the so-called LCCs. It already exists with one I regularly use, Brussels Airlines. The Legacy Carrier and Low Cost Carrier product will merge into what I consider Brussels Airlines to be: a Hybrid Carrier (you heard the term here first folks
).
