Spirit Airlines has instituted a "Carry on Baggage" fee of up to $45.00 per bag. Ryanair/Aerlingus are implementing pay toilets. Congress should prohibit these "surcharges" for the following reasons: It's unrealistic to warehouse passengers inside sealed aircraft and not provide a public toilet. Not everyone has a credit card and those who don't will be forced to "hold it". Carryon baggage are necessary for folks medications and valuables and anything not covered by the airlines Contract of carriage. We believe Spirit Airlines has gone too far. It's time for the Governmnet to prohibit these surcharges. The airlines have discovered a loophole. "Surcharges" such as baggage fees and other surcharges aren't taxed the same way as a base fare. What this means to the passengers is that the Aviation Trust Fund is not being funded as it would be if the airlines simply increased their fares to cover all of the unbundled costs. What does this mean to you? The Aviation Trust fund covers the modernization of the ATC system, airport improvements etc. Instead the airlines are making pure profit without participating in the future of air travel.
