Baggage policy for Chicago to Vienna flights

Baggage allowance on international Chicago to Vienna flights varies significantly by airline, route, and fare class — there is no single industry standard. Typical economy allowances on this sector are in the range of 23-30 kg check-in + 7-8 kg cabin, but low-cost carriers often charge separately for check-in bags, while full-service carriers on long-haul routes may include a second check-in piece. Business class typically doubles the allowance (40-50 kg).

Before you book, check the exact baggage rules on the fare-selection page for your chosen airline and fare. Extra baggage purchased during booking is almost always cheaper than at-airport rates.

Cancellation and refund for Chicago to Vienna flights

Cancellation and refund terms on international Chicago to Vienna flights vary substantially by airline, fare class, and how far in advance you cancel. Non-refundable economy fares typically allow only taxes + part of fuel surcharge to be refunded. Refundable / flexible fares cost more upfront but allow cancellation with lower deductions. Business and first class bookings usually have more lenient rules.

Rescheduling (changing your Chicago-Vienna travel date) is normally cheaper than cancelling and rebooking, but airline-specific change fees apply plus any fare difference.
