In light of the recent plot that was thankfully foiled by British authorities, more stringent carry-on luggage restrictions are now in place. It all began with several perpetrators who attempted to bring explosive liquids on board flights destined for the United States. The liquids were masked in sports drinks bottles. If successful, thousands could have been killed somewhere over the Atlantic. And because of the latest terrorist plot, airport security is changed
London Heathrow is a huge airport for onward connections. Unfortunately with the new safety regulations, luggage will be short checked to London. What does this mean for you as a traveler? It means that you will be required to pick up your luggage and check it in again instead of having it checked all the way through to your final destination.
For flights to / from the United States, United Kingdom, Canada, and several other countries, no gels or liquids will be permitted. This means no toothpaste or sunblock. The exceptions to this include breast milk and formula in bottles, small juice boxes for young children, and prescription and non-prescription medications such as insulin.
Expect delays. Even though time will tell whether these new security measures will become permanent, one needs only look at how long ago the "shoe bomber" Richard Reid attempted to detonate a shoe bomb on a transatlantic flight, and how many of us must take our shoes off at security.
Most of the airlines have listed the new security measures on their websites. However, if you'd like to read up on the official government statements then you can check out the TSA, and the U.K.'s BAA.
