Hi i have a inner ear infection .can i take a 1 hour flight on saturday thanks?

Possibly: If the infection is resolved and there is not pressure then it should be fine. Check and see if you can get your ears to pop by pinching your nose and blowing. If you can get them to pop then you know that the Eustachian tubes are functioning. If you develop pressure during the flight you can do this to relieve it. Taking a nasal decongestant spray before the flight would be a good precaution.
