Making airline reservations for a group

• Consider using a travel agent. They can take care of a lot of the headaches of travel.
• Buy a block of tickets way in advance and for more than you probably will need.
• There is a cut off date before which you can reduce the number of tickets without penalty. Then there is a cut off date for submitting names. Changes after these cut-offs are expensive.
  
• Do not allow latecomers, don't try to add tickets to the block, if someone buys another ticket it should be well in advance of the travel date. Changes like these are where troubles with the airlines happen.
• Make sure everyone has a photo ID, preferably a passport, and have it on them before heading to the airport
• Get a photocopy of each person's ID they will be using
• When submitting the names they must match exactly the photo ID
• When you get the list back from the airline, check the spelling of every name against the IDs
