Yes spandex, cheaper, of course. Don't forget to factor in an extra 200kg of fuel per sector for 8 sectors to attempt to catch up the schedule. And a day's full of disgruntled passengers who will probably find alternative travel arrangements. The coach option doesn't look so smart now does it. Show me evidence of where they've cancelled flights and combined them for the sole reason of it being cheaper and I'll agree with u.
