Be careful if you and your companion are on separate tickets. On a recent trip NBO-DXB-VCE, I was travelling with 8 family members and there were four separate PNRs and the agent therefore refused to pool our allowance. Ironically, being gold I had the highest allowance and the least luggage followed by my dad who is silver and also only had a 21" suitcase. Everyone else had to give us their heavy 28" bags to check in on their behalf and the process took an hour.
