Write to hello@willitboard.com. Reports of a limit that looks wrong are the most useful thing you can send.
The way to reach us is email: hello@willitboard.com. There is no phone line and no contact form.
That is the most useful message you can send. Please include:
Every report is checked against the operator's official page. If the figure has changed, it is corrected and dated like everything else on the site. Links to blogs, forums or luggage shops can't be used as a source, because that is how out-of-date measurements spread.
Suggestions for an airline, train or ferry to add, problems with the site, and questions about the privacy or disclosure pages all go to the same address.
Willitboard is not an airline, rail company or ferry operator, and is not affiliated with any of them. We can't see or change bookings, sell extra baggage, handle refunds or trace lost bags. For any of that, contact the operator you are travelling with.
Your address and your message are used only to answer you. They are never added to a mailing list, sold or shared.
