Thank you both and thanks for the welcome
That has set my mind at ease, thanks.
Can I ask why most on here prefer to fly with hand luggage only?
I will be joining a tour in Costa Rica the day after I arrive, so will not be able to wait more than 24h for my luggage if it were to get lost. I can try to pack light and take only hand luggage, but it would mean a lot of compromise.
Thanks for the information it has put my mind at rest.
