Purchased round trip non-refundable tickets BOS-LHR together with Insurance recommended by Norwegian during online booking process. Additional costs for check bag/seat etc also. Few months after booking unexpectedly became pregnant with due date around time of travel and by their own quoted rules I would be ineligible to fly. Waited past 12 weeks pregnant to confirm all ok so contacted Norwegian Customer Service to request cancel and claim on insurance. Agent told me I was covered as I had letter from OB/Gyn to submit. Few days later I was contacted by Norwegian, told that was not the case as Ins did not cover 'normal' pregnancy, only serious complications. I asked to reschedule my tickets for following year but Norwegian had already cancelled my booking. They refunded taxes part of booking but I am still $690 out of pocket for ticket/baggage/Ins prem fee. I have emailed and written to both Customer Service and Chief Customer Officer but consistently get a response from Customer Service Agents and told NO, not entitled to anything and they repeatedly quote their rules and regulations regarding 'non-refundable' tickets. Norwegian staff provided me with incorrect information at time I first contacted them which prompted their cancelling my booking and they took away my option to rebook. I now have no booking and no money as a result of their actions. I have asked for management discretion in this matter to issue an airline credit to re-book in future or a refund but nothing. In their latest communication I was told that they regard this matter as closed and even if I wrote again they would not respond! I have been polite throughout all my correspondence, cited details from their own website, tried to reach higher level management to communicate with but to no avail. Am I fighting a losing battle?
