For Major Airlines
The penalties and restrictions which apply to consolidated tickets are similar to those which apply to published web specials, sale fares and coach class airfares. Since 9/11, airline companies have become more restrictive on most kinds of tickets. The cheapest tickets for either published or consolidated fares are generally the least flexible and have the highest penalties.
The following chart is a guide only for consolidated international tickets. Airline restrictions and flight change penalties are subject to revision at any time.
