In general, each passenger is allowed one carry-on bag plus one personal item (e.g., laptop bag/handbag) on Iberia flights.
The carry-on bag must fit within size/weight limits (for example: max ~22 lbs / 10 kg according to some sources).
Checked baggage allowances (free) depend on your fare class, route and ticket type.
For short-haul/medium-haul flights (domestic/Europe):
Basic economy fare: often no free checked bag.
Higher economy fares (Classic/Optimal) usually include 1 piece (up to 23 kg) as the free allowance.
Business class fares generally include 2 pieces, e.g., up to 32 kg each on many routes.
For long-haul/ intercontinental flights (e.g., flights to/from Americas):
Economy fares may include 1 piece up to 23 kg or more depending on fare.
Business fares may allow 2 or 3 pieces (depending on route) up to 32 kg each.
Special additional allowance benefits: Certain loyalty status members (e.g., Iberia Plus Oro/Plata/Platino) and oneworld alliance status may provide extra baggage allowance.
Here are some examples of fees for extra bags or overweight/oversize. These are approximate and vary by route/fare class.
On short/medium haul (Europe etc):
Additional piece online: ~ €20-35 for the 1st extra bag for many fares.
Additional pieces at airport: ~ €45-65 each.
Overweight (23-32 kg) on Europe: typical fee ~ €12-15/kg one way.
On long-haul flights (e.g., to/from Americas):
First extra bag online: ~ €60; second extra bag online: ~ €80; third+ ~ €150 one-way in some cases. Airport rates higher (~€70, €90, €180+).
Overweight bags (over standard allowance) from Americas/Asia etc: Fee ~ US$100 (≈€75) one-way for Economy.
Maximum permitted weight per bag is often 32 kg in many cases; bags over 32 kg may not be accepted or incur high fees.
Maximum dimensions for checked bags: 158 cm (sum of height+width+depth) is standard threshold.
Here’s how and when you can add or purchase extra checked bags to your booking and what to watch out for.
You can add extra checked baggage via Iberia’s website or mobile app:
At the time of booking (when selecting extras)
After booking: via “Manage your booking” / “Customise your flight” → “Add extra baggage”.
During online check-in (often from 24 h before departure) you may see “Add extra baggage” option.
At the airport check-in counter or baggage drop: You may still be able to pay for extra baggage, but usually at higher fee.
Adding bags online (in advance) generally gives you a lower fee compared to adding at the airport. Example: “Additional piece online ~ €20-35” vs “at airport ~ €45-65”.
If you wait until the airport or the gate, you may pay the higher “at airport” rate, and the availability of the option may be limited (especially on codeshare flights or partner-segments).
Some user reports indicate: For partner-operated flights (not directly by Iberia) or when the first operating carrier is a partner airline, the online “add bag” function may not be available and you may have to pay at the airport.
Once you’ve paid for an extra bag, refunds are not allowed.
Check your fare class: Some “Basic” or promotional fares may not include any free checked baggage, so you must pay for even the first bag.
Operating carrier matters: On codeshare flights or multi-carrier itineraries, the baggage rules of the carrier operating the flight (or the most significant carrier) may apply — Travel agency so check accordingly.
Weight & dimension limits still apply: Even if you add an extra bag, if it weighs more than the allowed limit (e.g., >23 kg or >32 kg depending on route/class) or is oversized, you’ll incur overweight/oversize fees.
Time of payment: Adding bags early (online) is cheaper and more efficient than waiting until at the airport.
Iberia’s baggage allowances are route-, fare-class- and status-dependent.
Basic economy may have no free checked bag; higher fare classes often include 1 or 2 checked bags up to 23 kg or 32 kg each.
Additional bags and overweight/oversize baggage incur fees; adding ahead online is cheaper than at the airport.
You can add extra bags after booking (via Manage Booking or during online check-in), but doing so at the airport may cost more and be less convenient.
Always verify your booking details, fare conditions, and operating carrier’s baggage rules.
