I live in Spain, so whenever I travel I have to go trough Madrid Barajas airport (as it's closest to where I live). I've been flying trough here since I was born, so you can trust this review. I'll write this in the order that someone departing or arriving would follow. I'll focus on Terminal 1 for today. Departure: As soon as you enter T1 you can tell that it has it's age. The check-in area has a very low ceiling and is quite cramped. Despite this, it still gets the job done. Queues can be lengthy sometimes, but I've experienced that in many other airports. This area offers very little seating, as there is practically no space. Moving on to the security areas, the airport authorities have worked hard to renovate the checkpoints, and they have installed more modern equipment that helps lower waiting times (there is still a checkpoint that hasn't been renovated). Security is quite a pain though, as you have to take practically everything out of your bags, but there's plenty of space to put everything back without annoying anyone. Moving on, there is some retail spread out across the terminal (which generally consists of magazine stores, like Relay), but there aren't many places to eat. The "A" gates are in a pretty spacious area, and seating isn't a problem, but the older part of the terminal lacks some seating. Boarding is nothing out of the ordinary. Arrival: If you have the luck of arriving at the "A" gates, then de-boarding is really easy. You just walk off the plane and you end up in this walkway above the gates. When the walkway ends, however, things get complicated. There's not much signage, but it's hard to get lost, it's pretty straight forward. Passport control is slow, but airport authorities have installed a bunch of automated machines to make the process quicker. Baggage claim is also pretty straight forward. Exiting the terminal is quite easy, since you're really close to the parking lot, and to public transit. All in all, Madrid Barajas Airport is far from amazing, but it gets the job done.
