*disclaimer

Class refers to the Class of Service of your ticket. It is also sometimes called the Booking Class or Booking Code. The class of service is an alpha character beside the flight number and is indicated on your electronic ticket or passenger receipt as a booking class. For example, "F", "C", "Q", etc.

The flight number can be found on the ticket reservation and is generally a two- to four-digit numeric code.

Even without a flight number, general baggage allowances and fees can be found by filling in the information on the home page.

Most airlines calculate their bag fees based on three tiers of weight:

• 0 to 50lbs/23kg
• 50lbs/23kg to 70lbs/32kg
• 70lbs/32kg to 100lbs/45kg

Additional fees usually apply to bags over 50lbs/23kg.

The average weight of a checked bag is 30lbs/14kg. To get the most accurate baggage weight for your luggage, we recommend using a digital luggage scale. Please visit iflybags.balanzza.com for more information on digital luggage scales.

Airlines are continuing to update and file their baggage rules and allowances. If you encounter any errors or irregularities, please contact the airline directly or visit the airline's website for additional information.

Also, please view our iflybags disclaimer.

Integration for first and second bag pricing is easy – just append the flight data to the http://www.iflybags.com/bagservice.aspx and you will see the charges (if any) for 1st and 2nd bag shown in the browser.

Example 1:

http://www.iflybags.com/bagservice.aspx?fn=1&ar1=AA&cos1=Y&flt1=2020&dc1=MIA&dd1=2012-10-10&dt1=06:55&ac1=ATL&ad1=2012-10-10&at1=08:50

The example above shows that the fields are indexed: ar1, dd1, etc. Then index value is the number of the flight in the sequence of requested flights. So if you want to check potential fees for 2 flights, each field for the first flight will have a ‘1’ and each field for the second flight will have a ‘2’ and so on.

Example 2:

AA2020, on 2012-10-10 from MIA to ATL in class of service Y and
AA1945, on 2012-10-20 from ATL to MIA in class of service Y

Note below the fn=2 field: the value 2 means that there are 2 flights that need to be processed.
