It is inadvisable to fly when suffering from a cold. The reason for this is

the tissue around the nasal end of the Eustachian tube is likely to be swollen thus causing difficulty in equalising the pressure within the middle ear and the nasal/throat area. Pain and damage to the eardrum can result, particularly during fast descents

swollen tissue in the inner ear will increase the rate metabolic production resulting in hyperventilation

although the change in air pressure during a climb at lower altitudes is very small, it increases rapidly at high altitudes. If the tissue in the Eustachian tube of the ear is swollen, gentle descents at high altitude would result in damage to the ear drum
