He says, if the plane takes off at one o'clock, for example, from Bahrain.

And I arrive in Kuwait at one forty-one, meaning before the adhan of Asr.

Is it allowed to combine Dhuhr and Asr in Bahrain? Like this?

It is allowed, because a person does not know if he will arrive or not; these are matters of the unseen.

And as if he were in a car, for example, he enters Kuwait while still on the road.

At the border, for example, not like he has covered thirty kilometers from Sal, but he is far from home, far, he still needs time, he is still traveling.

Okay, and if the adhan for Dhuhr is called while he is still traveling, is it allowed for him to pray Dhuhr and Asr together as jam' taqdim, and then he arrives home, for example, at two o'clock before the adhan of Asr, puts his head down and sleeps? It is allowed.
