I was searching Sajha to see if there is some information about baggages on Gulf air and came across this post.

I am flying from US to Nepal on Gulf Air ticket.
Itenerary is as follows:

US to London --> American Airlines
London to Bahrain--> Gulf Air
Bahrain to Kathmandu --> Gulf Air

I checked the baggage policy of Gulf Air at : http://www.gulfair.com/English/info/Baggage/Pages/Baggage_Allowances.aspx

From what I understand, for Gulf Air Codeshare flights operated by American Airlines I can two checked in baggages.

For the cabin baggage, it says:

Economy Class:
One bag (maximum dimensions 45 x 40 x 30 cm or 17 x 15 x 12 inches)
Total weight: 6 kg

So, am I only allowed to take just one hand carry, and not a laptop bag or a back pack ?

I am also confused about the dimensions of the cabin baggage. American airlines allows to take 22 x 14 x 9,
and my cabin baggage is of this size. I won't have problem with American airlines, but will I have problem while taking the Gulf Air flight from London?

If you know something about this or have had similar situation please share.

Thanks.
