Welcome to the Lenovo Community !
Sorry to hear of your travel problems. Unfortunately your model does not have a diagnostic beep error code listing, but a similar beep error code for a Thinkpad would indicate that there is a problem with the motherboard or memory. Since you are traveling it is quite possible the laptop got bumped around and a memory module is no longer seated properly. I would suggest removing the back cover and then removed and re-install the memory module to insure good contact.
Your model's Hardware Maintenance Manual will explain how to remove the cover and the module. Here is a link to that manual for your reference....
