Hi My sister who will be traveling with husband and baby from usa to london and on wards to Ireland after a few days for the christmas holidays .She will have good baggage allowance with ba but then want to come to ireland with ryan air from stanstead as it is the closest airport to where they stay in london. The baggage allowance will be much less for the long haul flight that the ryan air flight , is there any way of getting her luggage to Ireland without incurring charges? She will have some santa and gifts also. If she came to heathrow would it be any better with aer lingus?. She wants to arrive to either cork shannon or Kerry all advice welcome. Can she forward her luggage by any other method?
