I've been sick with a sinus head cold and i'm going on an airplane for an hour and ten minutes. my ears are pluggedwhat can happen?can a doctor fix it

Its okay: You can travel, cough cold will get better within 5-7 days, if it doesn't get better you want to see a doctor.

Decongestant : You want to try to "unplug" your ears as much as you can so that the pressures can equalize, otherwise you may have a painful trip.Take a decongestant like sudafed before you board the plane and use a steroid nasal spray if you have one too. Chew gum-- they say blowing bubbles with bubble gum is a good way to try to open the eustachean tubes/ also take frequent sips of water as well.
