Constantly having MQD problems...they post about half or less than half of the pre-tax cost paid...and it's taking longer and longer for the Skymiles service center to fix...they re-que it and it comes back wrong again so they claim it has to be done a different way......I've said several times to the agents......if that's what Skymiles said I paid $254 but the ticket says and I actually paid $554 just give me a refund of the $300 difference and you can keep the mqd's and the skymiles ...I'm honestly tired of arguing over it..
