( CNN ) -- Following last week 's Malaysia Airlines Flight 17 disaster , the carrier says it will offer full refunds to travelers who wish to cancel their tickets , while those wanting to postpone their flights can do so without penalty . `` In light of the MH17 incident , Malaysia Airlines will be waiving any change fees for passengers who wish to make changes to their itinerary to any MH destinations , '' said the airline in a statement . This includes non-refundable tickets . The airline says passengers have until Thursday , July 24 to cancel or change their tickets , valid for travel until December 31 , 2014 . Meanwhile , the airline announced that it 's retiring the MH17 flight number out of respect for the 298 people killed on the Boeing 777 , believed shot down by a missile in rebel-controlled eastern Ukraine last Thursday . As of July 25 , the new flight number for Malaysia Airlines ' Amsterdam ( AMS ) -- Kuala Lumpur ( KUL ) service will be MH19 . Though such practices are common after a fatal airline accident , they 're not mandatory . Shortly after Malaysia Airlines Flight 370 went missing in March , the carrier renamed the flight MH318 . `` There are no changes to the frequency of our services and we will continue to operate daily services between Amsterdam and Kuala Lumpur , '' said the airline . Singapore Airlines apologizes for airspace tweet/FB post . Since the MH17 tragedy , all flights operated by Malaysia Airlines that passed through Ukrainian airspace have been rerouted . Other airlines have taken similar precautions . `` The usual flight route was earlier declared safe by the International Civil Aviation Organization , '' said Malaysia Airlines . `` International Air Transportation Association has stated that the airspace the aircraft was traversing was not subject to restrictions . '' Rival airline Singapore Airlines apologized on Sunday for what many social media users said was an insensitive series of tweets and Facebook postings relating to its own flight path . `` Customers may wish to note that Singapore Airlines flights are not using Ukraine airspace , '' said the post , which appeared on the airline 's Facebook page and Twitter account on July 18 . Responding to criticism of the post on its Facebook page , the airline responded : `` We are aware that our Facebook and Twitter update on Friday morning may have come across as insensitive to some . `` The post was in response to many requests from our customers who had asked for information about our flight routes for their upcoming flights with us . `` We recognize that the information could have been better communicated and we sincerely apologize if it had offended our customers and anyone else in the online community .
