I believe some of the big players have pulled out due to the risk reward profile of the bid (low or negative profit margins, penalties and escape clauses)
You’d think out of the lowest bidders CHC being the incumbents in KTA would secure the slot over a heavy EMS focussed Toll apart from a couple of ex offshore guys and their HOTC, maybe thats why they advertised awhile ago for more offshore drivers to put into their bid
