I'm booked on the HK, New Zealand trip for February 2012. Trying to check the baggage allowances for each flight. BMI from Edinburgh to Heathrow, then Air New Zealand, can you confirm what the allowance is for each flight, i've looked on the websites and its says 20kg hold baggage for bmi and 23kg for air new zealand, with a maximum size of bag for cabin baggage (and a weight limit of 7kg for air new zealand). Will my baggage be checked right through or will i have to collect and check it in again at Heathrow, i'm already getting nervous.
