That’s an excellent and common question. The short answer is: No, it’s not inherently rude to ask, but it can become rude depending on how you ask, why you’re asking, and how you react to the answer.
The key is to approach the situation with empathy, politeness, and a willingness to accept “no” gracefully.
Here’s a breakdown of the etiquette:
When It’s Generally Considered Acceptable & Polite to Ask:
- For a logical, practical reason: You’re traveling with a young child or a dependent person and are separated. Most people are sympathetic to families wanting to sit together.
- For a medical/accessibility need: You have a condition that makes a specific seat (e.g., aisle for mobility) significantly more comfortable or necessary.
- For a simple, like-for-like swap: Asking someone in an equivalent or better seat (e.g., window for window, aisle for aisle, middle for middle, or your aisle for their middle).
- Before everyone has settled in: Asking as people are still boarding, rather than after they’ve buckled in, stored their bag, and put on headphones.
When It Can Be Perceived as Rude or Inconsiderate:
- Asking for a downgrade: Expecting someone to take a worse seat (e.g., your middle seat for their aisle or window) without a very good reason. This is the most common complaint.
- Having a trivial reason: “I want to sit with my friend so we can chat.” (They can likely visit you mid-flight).
- Demanding
