The boarding process couldn't be more unpleasant really. We queue for half hour once we have arrived trhough the gate. They let us through the gates even though they have not opened the doors of the plane as yet. i feel like cattle. This time i decided not to bring any cabin luggage so that I could go through the gate last. Then I waited in the sun whilst everyone found their seats. At least 20 minutes. It was like torture. If i had a cabin bag - i would never have been able to put it above me, near my seat (which is always at the front) because the overhead cabin space would have been full. I need to work out a better strategy for next time or beg RyanAir and the cheaper airlines to work out a better boarding process. What do I do???
