I've seen this list, and quite honestly some of it is hopeless. For instance I always travel to the airport by taxi, so how on earth am I going to know the registration number.
What is a Travel Document number?
How many miles have I flown - I don't know.
The date of ticket issue appears to be asked twice.
The cost of fare, in a package deal is unknown
There are many more which are, to me anyway, pointless, and some risky, including giving your credit card details.(Q19)
In fact my wife and I had already decided that this Christmas holiday abroad would be our last venture out of the country for some time. The airport experience for our three holidays this year has been horrible. I know its necessary, but we've had enough. For the foreseeable future we will be holidaying in this country, and you never know, we may enjoy it more.
