Compare a fare, not a reputation
The airline name does not tell you everything included. A checked example at KLM: Basic on certain European routes does not include the same hand baggage as Light. Air France also lists different allowances by fare and cabin. Neither fact makes an offer good or bad; you need the exact ticket conditions. Apply the same approach to Iberia, British Airways, Transavia or a long-haul airline.
Define your needs before adding options
Write down what you will actually take and the constraints of the stay. Do you need checked baggage, a chosen seat or a changeable departure? Price both tickets for those same needs. Do not compare a bare fare with a package of unnecessary extras. Conversely, a modest upfront supplement may be useful when it replaces separate purchases you would make anyway. Check the return journey too.
Calculate the door-to-door cost
Hypothetical example, not a real offer: flight A costs €58, the bag you need €35 and the transfer €22, making €115. Flight B costs €94 with that bag included and €8 local transport: €102 total. B is €13 cheaper here. Add genuinely necessary costs, not imaginary packages. Check arrival time too: saving €15 may be a poor trade for losing half a holiday day.
Read what changeable actually means
A changeable ticket is not necessarily free to change, and no change fee does not mean no fare difference. KLM explicitly distinguishes these in its conditions. Check deadlines, potential charges and refund rules. Flexibility may be unnecessary for fixed plans but valuable when dates are uncertain. Keep the conditions displayed when purchasing.
Check the operating airline and connections
The seller and operating airline may differ. British Airways asks travellers to check allowances when partner airlines are involved. With separate tickets, also read connection conditions: must you collect baggage, change airport or check in again? Who helps if a connection is missed? Do not reduce this assessment to the layover time shown by a comparison website.
How we work
