The plane allows us to pray in an area on the plane and perform all the pillars of prayer, including standing, bowing and prostration. However, the space there is limited. Should we pray at our seat facing the qibla while not being able to perform all pillars or pray in the space given by the plane?

Ustadh AbdulAziz al-Haqqan

The space given in the plane not allowed otherwise. And you can wait until it is less crowded
