It's always a good idea to gather information about your trip well before you go. Use your travel agent or the transportation company as resources. Their Web sites and customer service staff can answer questions about the services you will receive during your trip. If you need information in an alternative format, ask your transportation company what they have available to meet your needs (for example large print publications or an electronic version). Do not assume that others know your needs.
It often pays to shop around. Services vary. Some may not be available everywhere. You may find that one company is better equipped than another to meet your specific needs. Ask questions. Compare answers. You'll get more control over your journey.
