A question unrelated, but also related to this; when booking a Vueling flight - is there a difference in Avios I get depending on whether I book it with Vueling itself or Iberia? If there's no difference, I would just book it through Vueling and then either fill in my Iberia Avios nr during the booking process, or transfer the obtained Avios from my Vueling to Iberia account.
Thanks!
