This is a great idea, however, the practicality of implementation may be a challenge with the existing setup of airports. The size of this device for just 1 individual possibly 2 (if couples are travelling) is relatively large in comparison to a row of chairs that 5 or 6 persons may sit in.
I presume that these airpods will be in high demand so the number of pods required for the airports will be massive. They will need to restructure their buildings or add on extensions to facilitate these devices.

Also, hygiene is crucial to a device like this. Either workers should to be hired to maintain the pod (which will increase the time between usage) or the device contains a self cleaning function after usage (which may drive up costs). People should not have to be in a strait between renting a hotel or renting a pod if this tech is implemented.
