It's great to drift off topic
I read this as a suggestion that Qantas et al should pay us to put up with being cramped on a long distance flight? On a second read I note that it might be suggesting some of us might still complain despite not having to pay? Or perhaps on third read that we should all stop complaining and just put up with poor service?
It's great to hear others experiences and advice.
On topic though!
Have we solved the mystery behind why airlines don't currently provide better ways to ensure all passengers have a level of comfort that respects our basic needs for personal space? There is only so much we can do once a flight has boarded.
It's self evident that airlines can and do respect some passengers differently to others. Whether this be in the concealed top tier lounges (that you get access to because of who you are IE Public figures, politicians or exceptional frequent flyer) or in seating and ticketing preferences based on how often you fly etc.
Notably one observation is that they do all try hard to assist passengers who have mobility or other recognised needs.
And you can if taller than most opt for an increased leg room seat. At a cost that may or may not be reasonable.
So why don't airlines offer a wider seat for some of us? And why don't they insist on their right to seat passengers according to the overall needs of the flight? If the relevant legislation needs some amendment to facilitate this so be it? The cost for a proportionally wider seat should be just that. No more than the extra width increase. In reality less because of the benefits of per passenger costs on each flight being less.
My guess is that until we demand it - probably through legislation, the current airline business model will prevail unabated. The encouragement of profitable upgrade options will remain. This is despite the airlines discriminating against many passengers by seating those of us with needs for wider seating where we cannot sit comfortably. Taking away from others the seat space they have paid for is no better in moral values. A modest increase in seat choice of 20% or 30% or 50% wider seats is totally possible. Some over wing two seats where there are threes or mid set threes where there are fours. I hope this does not defy Irish Logic?
