FR:
One cabin bag weighing up to 10 kg with maximum dimensions of 55cm x 40cm x 20cm ... Oversized cabin baggage will be refused at the boarding gate, or where available, placed in the hold of the aircraft for a fee of £50/€50 (fee subject to VAT on domestic flights at applicable government rates).
The FR limit is significantly smaller than IATA's recommendation, much to the chagrin of many passengers that fail to check before travelling. The 10kg maximum weight can also come back to bite you.
Tip: Make sure your carry-on is less than 10kg and meets FR's non standard size limit.
