Yes Luton Airport has dedicated armed Police at the airport that show up in the terminal as and when required.
Now that the Stansted subsides have gone the airport is now not so appealing to the airlines. Some people posting here seem to find it hard to accept that it was only subsides that kept some carries at Stansted.
according to el-al security they assumed LTN was only a third rate airport, not third world!
Only your second post and already you are lying
