How much will flight ticket cost from nigeria to italy,single trip.?

Your joking. No way can a Nigerian use a 1 way ticket to anywhere in the EC. Without the almost impossible to obtain documentation you will not be allowed to enter the EC. If that happens then the airline gets a fine so without the correct documents you will not be allowed to leave Nigeria.
A one-way ticket Lagos - Rome is €490 on Egypt Air or €493 on Qatar Airways. Those who have been issued a long term work/student or marriage visa can travel on a single trip ticket. Only short term tourist or business visitors require a return-trip ticket. Should you however have gotten an e-mail of an Italian whose money and flight ticket has been stolen and s/he wants you to send money so that a new one can be bought you can be sure to be scammed even if they have mailed you a copy of the passport. If you check this passport number on the list of lost/stolen Italian passports you will find out it is reported as stolen. http://prado.consilium.europa.eu/EN/checkValidity.html#ITA ..
Yeah I looked at Emirates $883.25USD one way.
