If LOT Polish Airlines charged you again for luggage you already paid for, the quickest way to contest it is to gather your proof first — your original booking confirmation showing the paid baggage allowance, your e-ticket/receipt, and the new baggage charge on your card statement.
Start by contacting LOT’s customer service directly with those documents and ask them to reverse the duplicate baggage charge, making it clear the baggage allowance was already included in your fare.
Use the online contact form or call the regional LOT support number (press “0” or say “agent” to reach a representative faster) and reference your booking and card transaction.
If support form responses lag or are ignored, consider filing a complaint on Xolvie to seek a resolution.
