Wondering if service is available to accompany me from arrival flight to departure flight within ICN? Have issues with walking distances, and anxiety about process to follow arriving from USA, then departing to Thailand with just 2 hours between flights! What cost would be involved?  Would also need for return flight on March 7. Arrive ICN on flight #KE660 from Bangkok at 5:20 P.M. Depart ICN to MSP at 7:25 P.M. on Delta flight #DL170. Thank you for any information you can provide!
