A shutdown of the Federal Aviation Administration will mean airlines no longer collect some federal ticket taxes, but other taxes would remain.

A round-trip ticket with a base fare of $239.26 from Peoria, Ill., through Chicago O’Hare to Raleigh-Durham, N.C., would run up taxes of about $61, for a total cost of $300.

Those taxes include:

Excise tax of 7.5 percent, $17.94

Four airport passenger facility charges of $4.50 each, $18

Four flight segment taxes of $3.70 each, $14.80

Four federal security charges of $2.50 each, $10

Total taxes: $60.74

The excise tax and the four flight segment taxes go away in a shutdown.

Total savings: $32.74.

Remaining taxes: $28.

Note: Taxes would be lower on a nonstop flight, because there would be fewer flight segments. Other taxes apply to international flights.
