easyjet: repeated entry of information they already have

As I observed earlier today, airline web sites are obsessed with making people re-enter information, apparently arbitrarily.

The following seems to be required for Easyjet, for an "existing" customer relationship, every time:

• country of residence
• selected from big list, involving skidding around on the screen that makes the victim feel sick
• should be remembered. If it has to be changed, should be type-and-choose
• victim is taunted with the text "tell us about you", when they thought they had logged in
• form with the following on one page:
• business / leisure
• title, first name, last name, age
• there is a button to "copy from contact details", but this doesn't do the "age" field.  Since they have my date of birth, they are of course able to calculate my age.  As well, the only values for this field are "18+", "17", or "16".  Is it a deliberate decision, to not fill this field based on the customer data, and to make the customer do it manually each time?
• whether you have travel insurance
• presumably this is an opportunity to sell you insurance, should you choose "no"
• confirmation that you are 18 or over (thus repeating, again, a previous step); and that you accept 3 sets of terms. Again, why the need to "agree" to these every time?

After this time-consuming admin schlepp, the customer might think they are done with re-entering information, but they are wrong.  There is more to be re-entered, in a separate session.  The customer might know about this, or respond to emails as the date approaches, warning them they won't be able to fly unless they re-enter their information.

• Add passport / ID details
• Add passenger information, consisting of the following fields:
• for passport, document type, number, confirm document number, nationality, country of issue, document expiry date
  
• these are all identical to last time. Why does this information not exist within my account, for re-use?
• easyjet deliberately increase the probability of incorrect information being entered, and confirm their malicious intent, by taking technical measures, for two of the fields "document number" and "confirm document number", to prevent the victim from pasting in their passport number
• the victim is thus humiliated, and made to re-enter, and then re-enter again, by hand, and it has to be by hand, their passport number, which easyjet already has, just because easyjet are vindictive
• the nationality field suffers from the "Afghanistan problem", in which a list of all countries is presented, starting with "Afghanistan", with no quick way to select the most common values, for example, in easyjet's case, British, or rather, in their list, "United Kingdom"
   
• date of birth
• again, easyjet should have this
• passenger contact details (email and phone number)
  
• these are remembered and pre-filled; well done easyjet
