I was trying to reach them via e-mail, Facebook messenger and by calling them - no outcome so far, no response, nothing. ... Cannot process with luggage booking on the website of Icelandair. It constantly shows an error message. For the moment, there is only carry-on included, and I would like to upgrade it to one extra bag as well.
I would like to have a possibilitiy to book a luggage before the flight. It would be stressless and money-saving.
