Use "Aggregate Functions".
Check the below link.

Can you please tell me the type of variable "interFlight"
The query you have has aggregated function sum(Total_Cost__c).
Here is the sample code:
AggregateResult[] groupedResults
= [SELECT AVG(Amount)aver FROM Opportunity];
Object avgAmount = groupedResults[0].get('aver');
Thanks,
