Sorry - as you didn't upload a sample file I did the formula just on here, not in Excel so didn't pick up my error. Try this instead:
Formula:
OFFSET('Air Detail with Reportable Fiel'!$A:$A,0,MATCH(A$1,'Air Detail with Reportable Fiel'!1:1,0)-1)
You won't be able to use this as a stand alone formula as the result is a range of cells, in this case an entire column. You would use this as part of another formula to refer to the column you wanted. Eg
Formula:
=sumif(OFFSET('Air Detail with Reportable Fiel'!$A:$A,0,MATCH(A$1,'Air Detail with Reportable Fiel'!1:1,0)-1),">1000")
