You will be fine! In fact, it is VERRY COMMON for doctors to prescribe benzos for people who are giant pussies and afraid the plane will BURST INTO FLAMES AND PLUMIT TOWARD THE EARTH WHERE IT WILL CRASH KILLING EVERY LAST SOUL ON BOARD...
When I worked as a pharmacy tech, there was a local psychitrist that advertised in the yellow pages as "Helping you overcome your fear of flying" (or some such crap) ... his treetment, for which I am sure people paid hundreds of dollars, was a script for 10 of the 15mg Dalmane (flurazepam) .. his directions were to take one the day of the flight, as soon as you woke up.. make it the airport and take one about a half hour before your flight takes off... the "extras" for for "jet lag" as his patients repeated what he had told them... it was rightfully recomended that they have someonme with them who was sober, because as I can personally attest to, benzos + airports can be an advebnture to say the least! (I would have muidded my flight to DefCon had a waitress not woeken me up!)
