"Leslie Walker of Plano, Texas, was planning to carry drinks for her 5-year-old daughter and 18-month-old son onto their flight from Dallas-Fort Worth International Airport to El Paso.

'It was really a relief to know that I didn't have to get here this morning and repack everything. It saved me a little time,' she said."

How is this helping Ms. Walker? She still can't bring drinks through the screening checkpoint. Was she planning on buying them at the high-priced airside stores?
