We booked a flight from Paris to Pisa in mid-September, 2013. We have been not been able to purchase "hold baggage" online. For an entire day we have tried from every angle to reach Easyjet with no success. We can get the size and weight restrictions, but cannot find a way to purchase the "hold baggage" online. The web site says you can only "manage your booking" if you booked directly online with Easyjet. We used a travel agent, and they refer us back to Easyjet. I believe Trip Advisor and Easyjet have some business relationship. We are hoping some TA traveler can tell us how to access Easyjet online directly. Better yet, help us get a phone number to reach a human working at Easyjet. Baggage costs are double when purchased at the airport.
