Excuse me if this appears a stupid request

Have 2 collums "From" & "To" and wish excel to look up a table that would
match the cell values of these collums exactly then enter the price in the
third collum of the table.
Example
a=Hotel name, b=Airport, want c to be a cost that is shown in a seperate
table that has fthe from, to and cost values
So when I enter the job details on my worksheet it automatically puts in the
price from the other table.
