6 pages! have not read all so I may be wrong - has anybody mentioned the necessity for TWO sets of steps to ensure optimum social distancing. I recently flew LGW-INV-LGW with LCC and found the cabin s-d procedures to be not fit for purpose - full loads each sector. I won't go into details but in these times two sets of steps should be mandatory, together with other COVID rules including maximum loading (middle seat free?) plus cabin rules which are currently guidance only in UK. A reasonable additional ticket cost should be accepted while train fares are typically double the average flight cost for domestic and European destinations.
As a former airline employee for several decades I flew frequently - both on and off duty. Since retirement my wife and I would normally fly several times a year for leisure, however following this experience we will not be flying again anytime soon.
Airlines need to accept that this 'new normal' is for many reasons indefinite. If they wish to keep customers they should be striving to keep them feeling safe from infection, otherwise, like us, they will find other ways to travel or stay at home.
