Jonathan,that is precisely what is wrong with this system,you refused travel to someone with a government issued ID card for which gives him access to some of the most secure areas in this country but not to an FR flight!The thing is You are not trusted with any discretion and this has instilled a "More than my jobs worth" syndrome,it is not Your fault but is most certainly FRs systems fault.Please don"t harp on about safety etc we all realise the need for it but there should be some leeway or else the system become discredited,I think (but not sure)that FR now accept military F1250s is this true? and if they do,do You not think that the system must be an ass for refusing them in the first place just because someone forgot to put them on the FR list of approved ID.After all it now appears that student IDs are not acceptable when previously they were.
