Does a father have the right to prevent his son from taking his wife along to drop him off at the airport when he travels?

If the father has no legitimate Shar'i reason to prevent his son from taking his wife to the airport when traveling, then he is not obliged to obey him in that. However, it is preferable not to disobey him to avoid angering him and escalating the problem, especially if there is no need for the wife to go with him.
