Should be no problem for your flights DavrosT, especially for such short duration use. Some alternatives you might find helpful too are L-Theanine at 200mg 3 to 4 times a day. Adding 100mg to 200 mg of chewable water Pharmacy-GABA from Natural Factors can really help with more significant anxiety.
You might find if you still needed some extra calming action on top of this Theanine dose, before and during your flight, your may well do fine with a much smaller dose of the Valium.
Learning to do relaxed rhythmic breathing exercises at will can really help with calming down in stressful or claustrophobia scenarios as well.
Best wishes DavrosT
