James always had an easy time on planes, he would pass out anywhere in a matter of minutes. According to his dad, it was a family gene passed through his mother’s side of the family. Regulus, on the other hand, he hated flying. During take off James saw him shaking and clutching to his seat out of fear. James, knowing about his distress during flying, tried his best to stay awake and care for him until Regulus was eventually eased to sleep.
As Regulus got older it was hit or miss with plane rides, either he slept for hours, or he didn’t sleep at all. Fortunately, this ride seemed more tame than the others, and he had managed to stay asleep for almost three hours.
Luckily once Regulus had moved in with the Potters, James would always help him. It didn’t matter that they weren’t even dating then, James would always insist on sitting next to him despite Sirius’ protest. Sirius would of course give up as soon as Moony called him other to their seats.
Per usual once the ride was over Regulus would never let James talk about what happened on the plane, embarrassed by the fact he needed help in the first place. Anytime James had tried to check in on him once they were on the ground, Regulus would shoot him a look that would shut him up.
Luckily, now that James and Regulus were dating Regulus didn’t even try to resist James’ help on the plane like he used to, and would instead lift the armrest to get even closer to him.
