When changing a flight date for medical reasons, most airlines will still charge a fee since their expectation is that the customer will attempt to receive compensation through insurance.
If however, the customer needs to change his ticket because of an uncertainty, they can ask the airline to freeze their ticket until a new date can be scheduled. They will still be charged a fee, but it may help avoid being charged multiple times.
Here is the process:
- Call EL AL and choose the option to speak to a sales representative
- Provide the ticket information and an explanation of the medical circumstances
- The case will be referred to a supervisor who may need you to provide medical documentation
- They will get back to you with an answer
