Thank you northernbelle and James James for supporting my words, that is exactly the thing, we are talking about Heathrow, not Gatwick nor Stansted (which as an example is getting rid of the FC with arrival of their new fleet) and airlines like BA, AA, entire Star Alliance, not easyJet, therefore we are talking about biggest and most prosperous companies of the world that have money to spend on treating their employees to comfier travels. Great you mentioned free upgrades which obviously make a lot of journeys in FC yet I need to say there is still a lot of business in FC ticketing. They would not keep 2 entire carriages of FC on the long formation trains for more than 2 years if it would not be financially beneficial to them. In Peak time sometimes you could not find a seat in FC whilst free upgrade customers were asked to free up seats to full paying customers. On new trains FC compartments will be shorter though there'll be 3 seats in the row instead of 2, so there will not be that much less seats.
