This couple would have been astonished at the IB priority boarding line on a Friday afternoon MAD to LHR a couple weeks ago. More people than group following two put together I think. I just waited until the end and joined when it was down to the last 5-10.

something else I witnessed though was a passenger being turned away, who protested he should be priority, and later turned up in the business class seat behind me. Wonder what went wrong there as the person checking must have seen his seat number.
