Flying in 3 days, ear congested after resp bug last wk - taking allegrad, mucinex, (guaifenesin) fluticasone, azelastine. anything i can do to clear this ear before flying?

Nasal decongestant: You may try an OTC nasal decongestant just prior to boarding the plane. This may not solve all of your problem but would be your best bet.

Yes, but some cost: AS you didn't state dosages, be sure you're taking maximum dosages-check with pharmacist re this. If still a problem, consider asking your physician for a brief course of corticosteroids which you will need to begin at least 24 hours before your flight. NOTE: there are some medical and psychiatric conditions for which such a treatment would be problematic--if so ,best delay your flight.
