最近,许多乘飞机的旅客反映,乘坐国内民航的航班安检比以前时间长了。提前两个小时到机场,不仅任何液体禁止随身携带,连打火机也不行。旅客的行李超过五公斤要办理托运,随身的行李必须符合民航新规定的尺寸,乘客普遍感到这些突如其来的规定过于苛刻,行业规定是否就不必征求社会的广泛意见就可以强制执行呢? Recently, many passengers traveling by air have reported that security checks on domestic civil aviation flights have been longer than before. Two hours in advance to the airport, not only forbidden to carry any liquid, even the lighter does not work. Passengers with more than five kilograms of baggage for check-in and carry-on baggage must meet the new requirements of CAAC. Passengers generally feel that these unexpected requirements are too harsh and whether the industry regulations can be enforced without soliciting broad community opinions.
