The Sun Country Airlines Chicago flight management features simple online tools for modifying itineraries, updating passenger information, or purchasing add-on services. Before arriving at O'Hare, travelers will be able to access their account to change a flight date, change seats or even purchase additional baggage allowance. The earlier changes are made, the less likely the traveler is to be subject to the higher gate modification rate and the greater the time for travel documentation to meet airline standards.
