It's The Day Of The Hearing! It's Time To Panic!
If you have taken the time to prepare your case properly and marshaled all the evidence, including confirming appearances of any witnesses by subpoena if necessary there is no need to panic. Follow your morning routines when you have a big speech or presentation to make. Your hearing is no different. If you have a lucky rabbit's foot, take it with you. Complete all the rituals you have to make you feel comfortable.
Be sure to give yourself plenty of time to make it to the courthouse. You never know what obstacles, such as snarled traffic or an accident, may cause a delay. If you are delayed call the courtroom and notify the clerk that you are delayed but intend to appear. You don't want your case dismissed because you thought you could make it. Arriving early also afford the opportunity for you to settle your claim against the airline without the need for a hearing.
If you can't make it to court on the date of the hearing and you have a very good reason, such as illness, unavailable witness, death in the family or other emergency, you must request a postponement in writing. It is in the discretion of the court whether or not to grant your postponement.
Remember the court clerk is your friend, so always be courteous to the clerk. The clerk can help you or hurt you. Your case can be first on the docket. You are in and out and on with your life. Or, you may have to wait until the end of the session. If you are having a bad day don't take it out on the clerk. If the clerk is having a bad day grin and bare it. Furthermore if you are in a jurisdiction requiring multiple hearings due to discovery or other motions then you will have to deal with that clerk more than once and judges typically hire their clerks personally. So keep that in mind when you are frustrated and feeling like snapping at the court clerk.
