Airline travelers would pay more to help finance airport projects under President Barack Obama's budget plan.
The president's budget released Monday would raise the "passenger facility charge" to $7 from $4.50 per flight to offset cuts in airport grants.
Just because it's in the president's budget doesn't mean the increased facility charge will fly. Some Republicans with a hand in writing aviation laws have different ideas.
Airlines are also fighting the proposal, saying it amounts to a $2 billion tax increase on the flying public.
