I'm a regular flyer with Easyjet and like the unallocated seating. When flying alone it means I have a very good chance of a seat near the front of the aircraft. For a 2 hour flight what matters to me is being able to get out of the airport when I arrive quickly. If flying with only hanx luggage, no need to wait for the baggage handlers and I prefer to go through immigration without having to queue behind everyone else.
