This change merely serves to cement my preferred use of Ember for those corridors in which your seat is otherwise cast down upon you by a psuedorandom algorithm on a small underpowered Android tablet.
I don't usually book before I travel simply because, as an enthusiast, my travel patterns are naturally spontaneous. In addition, it feels fairly antithetical to the entire concept of "concessionary travel" that I would be dumped into some random aisle seat next to a random guy eating a pungent Tesco meal deal (certainly not pleasant for a disabled autistic person) unless I paid for my journey, even if for a small fee. Whereas - if I book with Ember, there is not even a booking fee and I can sit wherever I please (which rewards people who arrive early - not a bad thing!).
