You can argue the toss all you like about load factors.
The truth is much simpler.
I have never been on Sqeezyjet or Tryonair. This time last year I had three trips booked and paid for at this time. One long haul to RSW, and two short hauls all to be done by the end of March.
This year nothing - it is not that I cannot afford it, the base rate cuts put money in my pocket overall, it is just that I am not inclined to do any travel.
This is common amongst the people I mix with.
