QR been giving me the run around. They promised a while a go to reoute at their cost and then a month ago when i decided to finialise the rest of my trip they told me they withdrawn the offer (without telling me)

they do offer to make me pay rerouting fee USD125, reissuance fee HKD80 and all new taxes which is a bugger for BA business flights as I HAVE A DONE3

the last sectors are as follows

BOM-xDOH-DXB

and they suggest BOM-xLHR-DXB - crazy but true, dont mind the transit in London but BA and LHR business taxes are eye watering

Thinking of buying another one way ticket from BOM on a one world carrier if possible and taking them to small claims tribunal.

do they have any defence to get out of this
