Not crazy at all. If travelling for leisure and time isn't a concern, I'll always make sure I'm travelling as comfortable (and horizontally as I can) - off to Japan next month and we're booked in a mixture of Qantas and Emirates first, rather than BA/ANA/JAL direct (which would have had to be in business due to cost). As we're away for three weeks, what's an extra couple of hours for a lot more comfort
