"When you catch a plane, you ___ check in before you board the plane." Please insert should where the gap is, per the AP Stylebook. Should expresses an obligation.
Or you could shorten it to: "When you catch a plane, you should check in before you board it." Hope that helps!
Should is not the right word here. It is "must." Must expresses obligation. Should suggests some flexibility ( "Well, you should check in first, but I guess it's OK to let you board") and there is no flexibility in boarding airplanes these days.
