Despite not changing terminals they had to do a ton of sprinting they said and just made it. While changing terminals may not be hard for you or other world travelers considering the stress my sister felt during all this, changing terminals was more then she could handle tonight. She is not a good flyer to begin with. As it turns out they all got put into the bulkhead seats of Premium plus... so at least their kids are happy. Last I heard my sister was still shedding a few stress tears. But their plane is taxing now to take them home.
