Now, passengers must pay a flat fee of $5.60 in each direction, no matter how many plane transfers are made to get from one city to another.

For passengers flying a nonstop round trip, that means the fee will increase from $5 to $11.20.

Passengers flying round-trip with a connection each way will see their fees increase $1.20 to $11.20 per round trip, versus $10 before the fee increase.

There's one exception: If you book that terrible trip with a long layover, meaning at least four hours when traveling domestically or 12 hours when traveling internationally, the fees start over. Passengers with that much of a stopover between their flights will have to pay another $5.60 for the next leg.
