I agree the prices paid by companies are usually too much. I've done a few Lyons-Rome for my company lately, and the ticket price was 833 euros
. Boy, I got a Paris-Santo Dominguo for less than that this year.
What really smashed me was the time I asked my company to do a Paris-Rome Rome-Lyons (I wanted to have a cheap WE at my parents'), they asked me to do the booking myself, and it costed the company.... 280 euros. Which means a third of the price for a longer trip. I'll never understand why they keep paying that much. (BTW, I should have told them it costed me 800 euros.)
