Shop around--best advice.
DALLAS - Some airline customers won't see savings this weekend even though several federal taxes on tickets have expired.

US Airways and American Airlines raised fares to offset the tax savings.

That means instead of passing along the savings from expired taxes, the carriers are pocketing the money while customers pay the same amount as before.

But other airlines left their prices unchanged on Saturday. Consumers could save money by shopping around.

The expired taxes can total $25 or more on a typical $300 round-trip ticket. For a September trip between Dallas and San Francisco, the cheapest American flight on was $24 higher than offerings from United, Continental, Delta and Virgin America, which did not raise fares.
