I need to fly from Hamburg to Gothenburg and it looks like CSA has a nonstop option on the day I need to travel.

The CSA website offers me a fare that doesn't include baggage for 56€/pp, or 88€/pp with a checked bag and a seat assignment.

Expedia will book me on to the same flight for $49 US, but only says it's P class, and gives no information as to whether baggage or seat assignments are included in that fare.

I assume not, but can anyone tell me or let me know where I could find that information?
