I reckon that those who wish to see p2f expand are those who have just qualified or are about to enter training and are desperate to justify their financial outlay to themselves.
Who actually operates p2f in the UK? Only really two or three low cost operators and occasionally BMI. The vast majority of European legacy carriers do not as they still value experience over unbridled optimism.
Lets see how many 200 hour wunderkinds get selected by BA or Virgin or GSS or Emirates etc before you all start wetting your collective knickers. You may all get your chance in the end but you may have to wait and you may not automatically occupy the RHS of a jet in front of those with experience. The past is no guarantee of the future. An airline filled with inexperienced cadets would likely draw the attention of the authorities as I understand, a certain loco in the frozen north has found out.
Just my 2 bob's worth.
