London Heathrow Airport Terminal 5

I recently had the opportunity to fly both British Airways and Iberia in short-haul economy, and talk about a 180-degree difference, especially striking when both are owned by the same parent company. While short flights don’t generally get much consideration, when one carrier offers so much more than another on the exact same route (namely between London and Madrid) for the exact same price, it’s probably better to go with the airline that will offer more and avoid the one that (spoiler alert) won’t even give you water.
