MCC 3043

Aer Lingus

MCC 3043 is reserved for Aer Lingus. Card networks reserve codes 3000–3299 for individual airlines, so issuers can see exactly which company a payment went to.

Airlines without a reserved code use MCC 4511. This category carries elevated fraud or chargeback exposure, for example because of future delivery, high ticket sizes or recurring billing. Expect closer underwriting and possibly a rolling reserve.

Related categories include MCC 4511 for airlines. Nearby codes include MCC 3042 for Finnair and MCC 3044 for Air Lanka.
