It’s 2026 and traveling in economy absolutely sucks. Some airlines make a tiny effort to appear a little more conscientious (Emirates e.g.), but SAS seems to have cut every corner possible in order to increase profit and screw over customers. This is the shitty world we live in. Travel used to be seen as a luxury. Nowadays, traveling in economy class feels like abuse. Like you’re being punished for not coughing up enough money. Despicable.
