Flights from Oxford to Palma | Oxford Airport Travel
To complement the Jersey service, it was decided to introduce a new short series flight to Mallorca running on 4 Saturdays in September - 3rd, 10th, 17th and 24th
But one can't book nor even get a price so they clearly haven't confirmed these September aircraft yet:
If you would like to receive some more information about our Mallorca programme for September flying from Oxford, then please complete the REGISTER YOUR INTEREST form and we will let you have confirmed prices as soon as these are available
Now it gets really funny ..... flights from Oxford to New York!
