There is no need to pay any more than £20k tops.
Frankly, the desperate low hour FATPL's will beg to pay hugely inflated TR's if they are going to get any contract at all.
I reckon Eastern could charge £25k for a TR and offer £16K contracts with no increments. Do you honestly think there would be no applicants?
Eastern are paying a very sensible market rate and deserve all our thanks for not taking proper advantage. They have some nice bases too.
