delta vs quatar

So sad. Airlines at each other's throats out there. The pilots and crew all have access to any airline if they so please and need to get where they need to get to fly a plane at any moment or provide services. Why would delta deny Quatar a gate. I'm angry about that. This is a plane full of children and you're holding it back. Unacceptable and should be heavily go against delta for that action. I understand competition between airlines and even have witnessed similar situations where an airline doesn't want to offer a gate because they got shafted in the past by another airline who refused to honor the agreement and kept using the gate longer than supposed to. I heard stories about that. But it's common practice and should be an unwritten rule that if there is a free gate and you have to let people off the plane so they can take care of their affairs and children, don't hesitate, DO IT. So wrong... what a dumb move by delta there....
